My two cents:
For anyone that cares about body connectivity, notice the reason he was able to get off that suwariwaza was because he had a more stable base in that move. Taking a quick look at the spine, hips etc, its easy to see why he pulled it off pretty easily.
Then he gets up and throws it out to mimic the muay thai guy's sparring movement. This simply has the effect of inducing a lot of sway into in his body. Basically he destroys his own balance.
If he knew how to employ the "base" that he posessed in suwariwaza in his walking/standing movements, maybe we would've seen something a bit different.
(IE maybe he wouldn't have sucked so much)
