Dunno about that one in particular, but I saw a couple in Thailand that were definitely staged. Stuff like, a guy missed with a head kick and the other dude just stood there and let him get back into fighting stance, or a guy who got "knocked out" with a jab to the face that sent him flying backward all the way across the ring, stuff like that.
I met an amusing fellow at one of these, though - Texan guy, former Marine, said he'd done over ten years of BJJ and boxing. He lived in the area, and apparently one night, having quickly figured out that all the fights at this place were fake, his friends goaded him into asking the manager if he could fight one of the Thai dudes. They figured it would be an easy win, since these guys were just doing WWF-type stuff, right? Well, he got into the ring and got his ass kicked so bad he couldn't get out of bed for a couple days. So i guess the moral of the story is, just because they're doing staged fights doesn't mean they can't do the real thing.
