The first one, maybe. Covering up just your footprints is really meticulous work, though, isn't it? The chances of either missing a spot or at least starting to erase the other footprints are too high, and it doesn't look like that's what happened.

...It's weird that there are footprints there in the first place, though. Like, did he go from there to the roof and then fall down? He sure didn't fall and then start walking around a little.
