Geoff Johns is quite a weaver of divergent plotlines, doing his best to say "This was an illusion, that character was lying, that other villain was mistaken." It might seem a little fanboy-ish, but I don't mind.
Heck, I'd like to do it myself, saying that every Dr. Strange appearance since AMAZING SPIDER-MAN #500 has really been Baron Mordo in disguise (with Wong forced to play along).
