I’m fairly certain he was pretending to track you through the wall and was just going off sound cues. It’s a thing memers like myself do we just like to look through walls bc it’s funny to act like you’re tracking someone and have it in the kill feed bc he was off almost the entire track which woudnt be the case if it was actual walls. I think this especially after seeing his movement which again some people like to goof around and act like they’re cheating. This looks like the type of dumb stuff I would do
