Where Alex was having a problem was his cue ball was getting batted around by other balls. Shane's was not as much.
It just seems to me Shane's break has a certain flow to it, where the cue ball bounces out of the way and settles. What I think is happening is he's making a downward stroke at the cue ball, slightly above the equator in relation to his shaft angle. This puts the cue ball airborne all the way to the one ball but with follow spin. The collision speed and angle pops the cueball upward and backward, then the follow spin resists and puts the brakes on -even if it collides with a lower speed object ball. Somehow his timing is such that he can avoid the corner balls that are coming up the table.
