I'm not sure as I don't follow the shows much. I can't remember most of what I see so (shrugs). I know for sure the Hapkido people do it since I independently discovered one of their move sets. Idea is to do a move that's fake then the exact opposite of that move right after. My two were: feign right hook followed by hard backhand; inside vs outside crescent kicks. They had even more. Hapkido people fighting non-Hapkido people using these techniques would be an example of deception. Also, flying submissions (my favorite) almost always involve an element of deception since a miss is so costly. Shinya Aoki does a lot of those. One in the video below shows that he looks like he's going to grab or control arms but lightening-quick jumps on one for an armbar. I similarly did fake clinches or upper-body take-downs to sacrifice throw someone into an anaconda or rear-naked choke. A related aspect I saw done esp in judo is you're trying to get them to react in a specific way to the feigned move so their own positioning or momentum aids you're real move. https://youtu.be/0GKneOIyXyA?t=1m36s https://youtu.be/0GKneOIyXyA?t=1m36s
