I myself am a subsciber to the mind theory. If he took his body, you'd have all the health and weaponry you left the last timeline with, which is obviously not the case when you spawn in on Rebellion levels. :)
: By the character(s) who are time-travelling, maybe. Everybody else in those
: realities are still there. Everything is duplicate across timelines;
: people, plants, and planets. This is actually a bit confusing with how
: Infinity does time travel; it seems the player's MIND alone is travelling
: back into his past body, so one wonders, what of his future body? Does it
: vanish, collapse dead, what? Doesn't really matter anyway, since those
: timelines are destroyed by W'rkncacnter. Alternatively, if the player
: physically transported his body into the past, there would then be two of
: him. Maybe he transports his future body back in place of the past one?
