Ah, OK. Meaning, maybe martial artists won't wrist grab in a particular manner... but it is possible that someone might do so, therefore it's not a bad idea to at least have addressed the issue at some point?Simpler than that. I am suggesting both techniques are viable. One doesn't negate the other.
I mean the origional idea was that Martial artists wont wrist grab in a certain way so therefore it is wrong to train from that wrist grab.
