I watched it again and I'm not really sure. (its at the 4 minute mark of video 5 if any wants to look).
He has two of them sets one down with a magnetic sounding click on a metal surface, he sets the other down on an electronic tablet and to your point it definitely seems to start the video. When he removes it the video ends, which backs up your point again. I'm not sure if he does any thing with the first one when he leaves. I still think they look like magnets, but I definitely see your point
