That means that there was elite dominate in those places.
Second stage PIEan Yamnya was R1b. My people the Ezdi Kurds who can be considered as proto-Kurds have also much more R1b, J2a than R1a in our ancestral homeland.
Also, don't forget that ancient IEans like the Hittites and Myceneans, similar to the Indo-Iranians, had also nothing to do with the Steppes. Those ancient Indo-Europeans were also full of J2a. So, it is perfectly normal that Indo-Iranians had nothing to do with the Steppes at all.
I'm sure that the ancient proto-Indo-Iranians had a lot R1b, J2a, G2a and even L in them (and also some other haplogroups).
