Okay, Ush, it's true that the BURNING as key is not clear from this. But what is clear that (if this is in the movie as well) that DISAPPEARING is not essential for ghostness... It comes from somehwere else.... ergo: neither is linked and it still doesn't prove anything that Anakin disappears in ROTJ. That was one of the key points of the argument. This proves the ghostness is caused by something else.
