Yeah, he doesn't really present any logic for that, either. As if he's starting from the discrete arrow keys and making an assumption that this is an optimal placement. I remember struggling with up/down on arrow keys as a child, thinking it should be more like a cross, with a space between down and up, or with the left/right keys centered on the gap between up and down. Edit: Echoing asdfs's comment elsewhere in the thread, I think that jkl; would be an alternative with actual, arguable benefits.
