There is no doubt you want backspin but all that really means is you struck the ball at the correct spot. Hitting 'top half' will result in top spin ground balls. Don't focus on backspin, focus on hitting just below center of ball with a 10 to 20 degree uppercut. And golf I think what he means about getting hands down is to drive them down while barrel is still up and then once in strikezone bat starts to make its swing path. There is no correlation between this movement and the chopping motion.
Barry Bonds, when asked how he hit the old apple replied that he swung down on the ball. The frame by frame slow motion videos showed that he swung 5-10 degrees up. This is the "level" swing Ted always talked about and that is to mirror the path of the pitch.
