in general, "full power", "giant scale" and "down line" don't mix. pick any two, but not all three
You'll see Joe apply some power in downlines with the 104 and 87 and such, but he's actually doing a little bit of a magic act in going from stall to a speed that the plane normally sees at full throttle on the flat, then he starts pulsing. ie: he's actually being quite mindful of the speed. So looks like he's doing the big no-no, but he's actually presenting the speed of a horizontal maneuver in a different way that looks more awesome.
