Well, at least that's not the worst version of those techniques I've seen.
Maybe not the worst but far from what I would say a decent version of it. Lets face it, even if the guy knew how to, he would have problems applying the waza considering his weight problem. His kamae is awful and his balance is all over the place. Those locks wouldnt work on me even if I didnt actively resist them. Imagine how it would fare against a resisting opponent...
