This is funny, Most bikes that come in the shop I find are way under damped ont eh compression, and WAY over damped for rebound.if you think about what he said for setting up rebound, setting it by compressing then trying your best to make your body a dead weight, you are going to need very very fast or close to no rebound damping to get it to oscillate.
he does say there that most people run their rebound way to fast, which i dont agree with at all. most people have a fear of running fast rebound, which is just stupid.
I have always looked at rebound like this, its what is holding your tire on teh terrain, ifs its too slow, your going to load up, and basically shorten your travel, lower your effective sag, and change the Geo on your bike through the Stutter, too fast, and youll be topping out, and bucking.
I keep mine pretty fast, I slow it down just enough to keep it from bucking, stick to the terrain like mad...without limiting the ride.
