Well, we don't really have any way of knowing that. In theory, it could be so, but our theories don't matter, only Kishi's. He can explain it any way he wants, if at all.

I seriously doubt that he is dead yet though. Deidara warned them about Naruto, so it is pretty safe to say that they will encounter Naruto before they die.
