he rules out the spots that you can't end up on based on his count; i.e. in an odd number of moves you cant end in a spot that would require an even number of moves.

well yea, but how

math

pretty basic graph theory. make a picture of points and then graph various paths. there's lots of math about the possible paths. this is how computer networks work

you can only move one spot per count up or down
counts are even or odd

you need me to go farther than that?

Also, I would have been more impressed if he had accurately predicted I would be bored out of my mind by the end of that video.
