So the U-152 could have been a larger percentage of the actual migrating group. It would be informative if they isolated the yDna of that actual migrating group so more valid conclusions could be drawn.
Still, the U-152 is almost all L2, which provides a valuable clue.
There seems to be some clustering around the Carpathian sphere in some, but this needs to be figured out. Like the best case for E-V13 in Britain and to which other individuals from the study he's closest to:
The most relevant is imho I14465 E1b1b1a1b1a20~ E-BY4643 because of his subclade:

And the most interesting part about him might be with which other samples from the studies he clusters, and their yDNA:

A lot of R-L2, so they are associated, like expected, with R-U152!

Upstream its being found in an ancient sample from the Polish Carpathians (!):

Sample PCW070 from a Corded Ware/Epi-Corded context near Przemyśl, Podkarpackie:

The Corded Ware was from this study:
https://www.nature.com/articles/s41598-020-63138-w
The study is also interesting for the context of the region:
All individuals studied here are associated to burials of the CWC and BBC complexes. Based on the geographic location and the strontium isotope analysis we identified four different territorial sub groups, and based on the genetics we identified at least two different groups within our sample set. The mtDNA and the Y-chromosome data provide a slightly different picture of the genetic variation in the region contrasting earlier studies of individuals from corresponding archaeological contexts from other regions of Central Europe. In contrast to observations by Juras et al.12 we did not find mitochondrial lineages specifically linked to Yamnaya pastoralists, instead most of mtDNA lineages found in our sample may be associated with European Neolithic farming groups as is the case for the Western Corded Ware sample in the earlier study12. Our results would indicate a stronger continuity with earlier Neolithic populations than previously observed. In other words, our study detected traces of an evident ?incorporation? of local individuals into the migrating groups. However, the funerary rituals seem to have been affected in limited extent as the burials exhibit the typical CWC pattern in all cases examined.
And like I say all the time, the most likely path for E-V13 to make it was to be incorporated into the Epi-Corded groups, in the Carpathians, possibly as specialist miners and metal workers, but in any case they were. If those two would stem from the same context, that would be big and E-V13 would prove that male lineages in the Carpathian region were incorporated too, together with a majority of females, by the local Corded Ware and Bell Beakers.
This was a different Corded Ware context:
he Y chromosome haplogroup lineage R1b-M269 or R-L11 are characteristic of Yamnaya and Bell Beaker individuals5,10 and they were particularly widespread throughout Eurasia in the Bronze Age and thereafter38. Curiously, the haplogroup is uncommon among other published Corded Ware Complex individuals from Europe (Germany, Poland, Bohemia, Estonia, Lithuania)6 and is associated with the later Bell Beaker communities5. We see the inclusion of the Yamnaya genetic signals but again in a different manner than what has been shown in adjacent regions. These results indicate a higher level of CWC continuity with earlier Neolithic individuals than those previously studied.
Also interesting:
Bell Beaker individuals from Pełczyska mostly favour German, Polish (lowland) and Estonian CWC as well as German and Czech Bell Beaker populations over Steppe ancestors (Table S16). Interestingly, in contrast to CWC individuals from south-eastern Poland (Group I, II and IV), they share significantly closer affinity to Neolithic Iberian, Italian, Hungarian, Swedish, Polish TRB and Brześć Kujawski group populations (and nonsignificant but positive affinity to Polish Globular Amphora) than Yamnaya, pointing to possible continuity between this group and earlier populations. The genetic specificity of the population associated with this process shows similarity to the features of the BBC complex in Central Europe dated ca. 150-200 years later

And the J-guy seems to be: https://www.yfull.com/tree/J-Z597/
So a J-L283 Pannonian-Illyrian most likely, which travelled with them, either in Urnfield or Hallstatt - or even staying, depending on where they found them.
