You are right, but I don't think that he was referring to power and spin potential of the different grips so much. What I got was that he meant since you are using less racket-head speed to brush up for topspin, the ball has more pace for the same effort. At the same swing speed, less topspin equals more pace. That is what I think he meant at least
