It works in MMA too. Actually, I think that the last incarnation was in the last Ultimate Fighter finale, done in a guillotine choke by that guy from Spokane against that English guy. He didn't have the neck, just had the jaw. Specialists can break your jaw just from the force of their squeeze, no joke. It happens at the Abudabi tournaments regularly too. Think about it, these guys practice squeezing with their arms all day. And the average MMA fighter does not have anywhere close to the amount of experience in fighting off submissions that pure BJJ and submission wrestlers have.
I'm not even a particularly good BJJ guy, and I've tapped guys out just by squeezing on the jaw. It's definitely a strength move. Another effective move that is legal in MMA, but not in BJJ or most submission grappling tournaments, is the neck crank, from either a guillotine or RNC position. Actually, I demonstrated how fast the guillotine version is on an SF member when j and I were in SF working on the new system. Once you've forced the neck into position (or tricked the guy into the position), the tap comes nearly immediately.
