The only difference between what was on the video and the original (as I learned it from Grandmaster Kim Soo) was,
1. they added a small block after the wedge block (after the knee-head smash part),
2. the backing-up forearm blocks should be with a knifehand,
3. after the spinaround forearm block (should be a backfist), what they did as a rising block should be a clearing block (as if someone grabbed you arm).
But, these are very minor interpretation differences and the structure of the form is no different at all. If someone practices this form they really can't mistake it for anything else.
