  It's subtle, but the mirror images are often "wrong". Like at 0:12 the yellow shape is laying on its side, but in the mirror it's standing on one of the short ends. At 0:28 the rightmost woodcube is laying on the bark, but in the mirror the side down is the chopped side.

And for some of the shapes, it works well even when looked at with two eyes (which supposedly should tell your brain the trick) and from not the perfect angle.
