up, then back down, up again, then back down, card shuffling back and forth, this card over this card, and back under this card, did I just see him reverse some cards? was I supposed to see that? whoops, back up and down again, ok, they are all face down now, wait, weren't they face down to begin with? I mean, cuz I saw them face up when they were held low, but saw the backs when they were held up? wait, was it the other way around? Can't remember.
These are the confused thoughts I had when I viewed your video...
