As it stands, not one of the people in the videos you attached teaches in NY. More importantly, it is more than disingenuous to suggest that any one of them would survive 5 seconds against anyone with any combative skills to speak of. I wouldn't even want to see a photo of the aftermath should they face anyone on the street who was trying to hurt them.

Of course, they may be wonderful teachers instructing at wonderful schools with wonderful students while being, well... wonderful to follow. But practical or combative or real self defense... not likely.
