First, the video is 4 years old. Second, it's clearly a joke, as noted in the comments.

Can you a) link to the video and b) tell us if it's genuine duplication or just ghost blocks? Rapid piston movements does sound rather like ghostblocks at first.
Maybe a screenshot with the contraption would also be helpful, better than that YTer's video.
