I would have to disagree. Snp/str/autosomal branching + carbon dating samples are extremely informative. For example z-2103 and L-51 branch from L-23+, it would make sense to place L23+ L51+ Z2103+ in the same geographic region, str/snp/autosomal connection.
Until very recent we did not have a proper understanding of Caucasus and speculated on the main Yamanaya autosomal components.
With each new sample our understanding is improved[we can ask proper questions]. For example, we can see that Georgia @26000+/- [basal Caucasian]years ago had different composition than CHG; all located in a region near Yamnaya and Maykop burials. While WHG represented by Villabruna cluster is a R1b branch.

To address this imbalance and to better understand the relationship of Europeans and Near Easterners, we report genome-wide data from two ~26 thousand year old individuals from Dzudzuana Cave in Georgia in the Caucasus from around the beginning of the LGM. Surprisingly, the Dzudzuana population was more closely related to early agriculturalists from western Anatolia ~8 thousand years ago than to the hunter-gatherers of the Caucasus from the same region of western Georgia of ~13-10 thousand years ago. Most of the Dzudzuana population's ancestry was deeply related to the post-glacial western European hunter-gatherers of the 'Villabruna cluster', but it also had ancestry from a lineage that had separated from the great majority of non-African populations before they separated from each other, proving that such 'Basal Eurasians' were present in West Eurasia twice as early as previously recorded. We document major population turnover in the Near East after the time of Dzudzuana, showing that the highly differentiated Holocene populations of the region were formed by 'Ancient North Eurasian' admixture into the Caucasus and Iran and North African admixture into the Natufians of the Levant. We finally show that the Dzudzuana population contributed the
