Just watched the video.  It sounds too simple, no adjustment for squirt, cue ball coming in from different angles, etc.  I don't see how it could possibly work for all shots, ie -  for a thin cut with no english you are basically aiming the center of the cue at the edge of the OB.  
I may play around with it and try to keep an open mind, but conceptually I don't see how this could possibly work with all shots. With an angle approaching 90* and no english, the the cue needs to be pointed at empty space near the OB...
