The same was said of Bruce Lee, particularly in the filming of the Green Hornet episodes. I've read a few accounts where they said they eventually had to speed up the cameras for Lee since at normal speed, he'd walk up to a person, there'd be a blur or nothing at all, and that person would fall or fly. By recording at a higher speed and then slowing the camera playback down to normal speeds, the camera was able to capture the motion and then play it back so we could actually see what Lee was doing. Basically, speeding a camera up during recording slows the action down when it's played back at normal speeds.
In contrast, you could look at a Van Dumme movie where either the camera has been slowed down and/or the playback is sped up to make him look faster than he really is.
For some martial arts movie geek fun, get the Enter the Dragon DVD and watch Lee's fight scene with Bob Wall (Ohara)...particularly the beginning techniques from the reference point. Watch that sequence frame-by-frame and see how many moves Lee really does. A good example of trapping hands, by the way.
