I had to test your observation before answering, and it looks like the bubbles are actually rising to the top, they are just so thick that it moves the beer in waves. Those waves are going down as the bubbles go up. But from a foot away it does actually look as if the bubbles are actually travelin down. My suggestion.. have another and look closely.

The bubbles actually sink when they are near the glass surface, and rise near the center of the glass. So they actually circulate in a current.
