So far the best answer I've seen is that any time a separate ship's ability triggers a reroll, that separate ship is the "source" of the modification (regardless of who is instructed to reach out and change the dice). In the case of Etahn, Howlrunner, M9-G8 , Palpers , etc, they are the reroll source, not the attacker/defender. Thus they work with Snap Shot and against Omega Leader, etc.

If there's another really good counter-argument in that thread I'll relay that here, but so far that's the explanation that makes the most sense. And a solid-feeling answer is not common enough in FFG text, so I'll take it. :D
