It's just a list of the Move Tutor Moves that are in the game, they're each associated with a number that they're listed in, and the source that gives them out. So for instance, Move tutor #1 gives out Bounce, which would be Source #1, #9. You can see the move numbers and sources for each Pokémon right
here.
True, it does make sense if you put it like that, it's just kind of odd it got that move over the much more "tricky" Knock Off.
Edit: Move Tutor #2 coming right up!
