Correct, in so far as the spread of the languages. However, the spread of the populations and the relatedness of the peoples, discovered through
genetics, was a different path. Europeans speak an indo-european language, but aren't, necessarily, descended from the group of people that
initially spoke proto-indo-european.
Consider england. Everyone speaks english. Including black immigrants from west africa. Same language, different genetics. ALso consider that
english spread into africa, or that spanish iand portugeuse are spoken amoung non iberian populations throughout all of south america
I was pretty sure that the Aryans migrated from the region of the Caucasus Mountains throughout Asia, Europe, and the Middle East. Thereby
leaveing their genes all over the place.
The original homeland of hte tribe that spoke proto-indo-european isn't known, some specualte that it was the caucus, others that it was a bit north
of that, others that it was in central asia, etc. Their language spread, certainly, how much their persons spread is another question.

Actually in reviewing some information, it looks like there is some research that supports a closer relationship with europeans, implying the spread
of a population from the center to both regions. BUT, there are still other studies that contradict this strongly.
This wiki entry is actually a really good summation of the different papers that have been published.

But also note that it is basing some of its infomration on their having been a "Kurgan Culture" in central asia, kurgans being burial mounds. This
kurgan hypothesis is also on somewhat shaky grounds.
Also notice:
South Asia is logically the ultimate origin of M17 and his ancestors; and sure enough we find highest rates and greatest diversity of the M17 line
in Pakistan, India, and eastern Iran, and low rates in the Caucasus. M17 is not only more diverse in South Asia than in Central Asia but diversity
characterizes its presence in isolated tribal groups in the south, thus undermining any theory of M17 as a marker of a 'male Aryan Invasion of
India'"
not sure. 
kinda cool.
