I think we need much more researches to validate this migration.
First of all, we need seima turbino aDNA. When this IE people migrated into south asia, I think ST dominated whole Eurasia like mongol.
Second, no andronovo artifacts were found near south asia.
Third, several scholars already mentioned that east andronovo culture was much older than west andronovo.
Fourth, harvard scholar directly connected andronovo steppe admixture to modern northern indian. Problem is we recently knew that tianshan sample’s steppe admixture has nothing to do with afanasievo. In other words, modern northern indian can get steppe admixture from scythian, white Hun and etc.
Moreover, there is bronze age culture in south asia, copper hoard which I think they have altai culture and chariot, being related with mycenaean and the celt. We need this aDNA.
I explained here:

Andronovo has two cultures of West Alakul (around 1800bc-) and East Fedorovo ( around 1700bc -). So traditionally andronovo culture migrated from west. However, east zevakinskiy-BA has the oldest example of R1a in ancient DNA from Central Asia which is dated to 2132-1940 calBCE (ID I3770, Narasimhan 2019)..
