As the plane slows down the fuselage acts as a wind break. This results in reduced and finally almost NO control over the elevator some time before the wings actually stall out.

At a slightly faster speed the air will follow the fuse back to the tail, giving you control.

What he is saying is that you come in a bit hotter, and at a steeper angle, then once over the threshold, bring down the throttle while holding it just over the runway until the plane settles in. This will be a steeper decent under power than what is normally done.

Typically with a steep decent you chop the throttle. In this case you don't want to. You need some power on.
