As far as I know, that is fake. There is an elastic string attached to the tee. A ball cannot bounce back into place twice naturally due to momentum. Not to mention, the ball slowed down before touching the tee again.
Actually, no, because he swung the bat forward only once and that was on the first shot. If he swung it twice, then maybe that would be the case because his secondary backward swing would slow the impulse of the ball, but alas, he did not do so.
