The differences between Centum and Satem are not only because of some vowel and consonant changes. There're many words that both groups don't share with each other.
I've got this frim wiki: "Balto-Slavic is largely satem but evidences centum development in some words, suggesting that "Satemization" was incomplete or operated according to different principles than in the other Satem languages."

So there can be a 'Satemization' or 'Centumization' of languages!
Sorry, did you even read what I wrote? The change is not just "some vowel and consonant changes". This is much more fundamental. Sound laws have no exceptions.
Also Centum languages are "nominative" and "accusative". But not all Satem languages are "nominative" and "accusative". Some West-Iranic languages, like Kurdish, are "ergative" in nature.
According some scholars the Proto-Indo-European language was an "ergative" language, but some scholars refute this hypothesis.
Stop throwing around words like these without even really knowing what they genuinely mean. It's the first time I've seen anybody claim Proto-Indo-European was an ergative language. Virtually all Indo-European languages are accusative, and those that show signs of ergativity clearly have developed this secondarily.
In any case, I fail to see how this relates to genetics and haplogroups.
Fact is that the Rigvedas were written in Sanscrit and Gathas in Zoroastrian scriptures were witten in Avestan. Both langauegs are Satem.
The only thing that this tells us is that the Centum/Satem split was already complete by the time these texts were written. Please consider that Satem is NOT the original state, and neither is it in Centum. However, the sound in the Centum languages is generally closer to the original than in Satem.
