Haha. So it begins. Damned time lines.
Marty came back and saw his past self (well, present self) escaping from the Lybians, but he'd returned to his present from the past. So they should have called the movie Back to the Present, but anway. He was just watching himself about to go back in time the way he just had.
Unless you're talking about BTTF 2, and not the original. Maybe there's something I've forgotten about.
