Wyoming's death is confirmed. Recovery One takes place after Out of Mind and during Season 5, which would explain why Wyoming encountered Wash. After he left, he went to Blood Gulch and was killed by Tex in Episode 100.

Someone mentioned that a clone could've been the one who encountered Wash in Recovery One, but I don't think his clones were created until he was at Blood Gulch (Episode 98), making it hard for one of them to escape (or want to escape) and return to briefly fight Wash.
