Can we draw the following hypothesis from the context?

Context:

I ducked so fast I wasn't sure whether he 'd seen me or not, but it gave me a prickly feeling just to imagine it, so I scuttled for the door and legged it up the spiral stairway three steps at a time, just in case. As I ran, I remember thinking stupid thoughts like. How did he know I was up here looking down?

Hypothesis: he was up there looking down
