That's not clear at all but you would argue with a rock if someone came by every now and then and turned the rock over to make it appear interested.
The clip begins with the back move to the left side of screen (from our perspective) and Williams moving to the right side of the screen. He doesn't change direction at all. He stops and then steps backwards.
