About Mallory, also read his recent work which was published this year: "The Impact of Genetics Research on Archaeology and Linguistics in Eurasia" where we read about Indo-European homeland:

Genetics has pushed the current homeland debate into several camps: those who seek the homeland either in the southern Caucasus or Iran (CHG) and those who locate it in the steppelands north of the Caucasus and Caspian Sea (EHG).

It seems he is also among advocates of an IE origin in Iran!

I wrote an article about the origin of Indo-Iranian culture: Indo-Iranian culture originated in Indo-Iranian lands (East of Iran, Afghanistan, Pakistan and north of India)

Caucasus or Iran, and he also seems, at least in the sentence you are quoting, to be just describing a fact (the 2 main hypothesis advocated by scientists today and plausible by archaogenetic studies), not stating any personal opinion.

In any case, no geneticist in the entire world today doubts that the IE expansion happend via the Western Eurasian Steppe migrations during the EBA and EMBA. It's pretty much consensus. The issue is just where PIE was first spoken, not where it was last spoken and started to expand and split into different languages.
