I can't remember where I heard this, though I think it was on the Ortiz academy website forum a while back, but someone asked Sifu Ortiz about some of the forms on that video series.
And if I remember correctly some of the forms he said were made up just for that video series and were not taught at his academy. The videos I beleve were just a taster for people to get an Idea about what 7*Mantis looked like without giving away the real forms incase people copied them and started teaching.
A wise man knows, that to know is to know that to know is not to know
