Assuming a long distance between PIE and PU speakers puts limitations on possible scenarios but it must be remembered that the present distribution of Uralic speakers is the result of a long distance migration. An earlier long distance migration in a different direction is therefore plausible.

The issue we now have if we insist they had such a great geographic separation is that the similarities to Pre-PIE in Uralic are still there from the birth of Proto-Uralic. Therefore asserting that Proto-Uralic's homeland is Yakutia means the Pre-Proto-Uralic language came from the west, and this more western location is where they picked up speech that brought the similarities to PIE in Proto-Uralic.
