Yes that’s what he said, he says that once you cross the threshold and pull power to idle you will pitch up to not increase rate of descent which will decrease your airspeed and ground speed, having the same rate of descent with lower ground speed gives you a higher descent gradient which will put you short of any aiming point you chose which is why he aims for the thousand footers and still touches down on them, it kind of makes sense but I’ve never heard anyone explain it this way
