In the original position there are 5 heads which have parts on the bottom paper and 1 that 's fully on the top right (the 1st head of the top right paper). Total 6.
When the movement occurs, the 1 head that was fully on the top half goes and sits on top of the first head part from the left. Still 5 heads on the bottom but now for a total of 5 since the 1 extra is now sitting on top of the bottom left head part

Thanks for the explanation jazzc! I was clicking back and forth between the two images for literally half an hour *chuckle*
Pretty good videos on that channel
I understand the explanation , yet I still can't "see" it , Head =Warped. Amazing trick though, I'm always in awe at the people who think these tricks up.
Thats easy, in first half, there were 2 faces which didnt have any counter-part on lower cut of the paper...
@ShadeDream: Thanks for the compliment, but it doesn't have to do with programming; rather with how to attack a problem. In this case, what you have to do is find what doesn't change and work your way from there
It's an optical illusion (or something like that). The hat and the mouth which looks like a nose (or vice versa, green arrow) is what confuses you to see another face which doesn't really exist.
