This is one of the more absurd videos I've seen. If you're in a situation that is truly life-or-death-serious (this guy really wants to kill you or something equally serious) don't teach people to rely on finger locks alone and don't teach people ineffective technique like letting go of your lock to try an un-leveraged 'neck snap'.
Advice on small joint manipulationThe finger lock is a sound technique, but is also a very weak technique in terms of mechanical advantage. Those who are determined, mentally incapacitated (mentally unsound or on drugs) or otherwise just-don't-care will take broken fingers if it means being able to accomplish their goal. You can find numerous modern examples as well as throughout history about this. I've heard first-hand from multiple prison guards that they have altered what they train because prisoners have no problem taking a broken finger or wrist if it means getting to hit who they really want to hit. These guards don't go for finger locks or ever wrist locks anymore.
That's not to say it's ineffective though. Small joint manipulation is a fine place to start, but not to stop.
Snapping necks"I let go, release the jaw.. push and pull back." Do not do this. If you have a lock and it is working, do not let go of it to do something ineffective. Any time you change what you're doing there must be a transition. Your opponent must be stunned, locked up or otherwise incapacitated. Transition with a flow into another lock or a strike, do not just let go.
This neck break will never work because she has no body control or leverage of any sort. The guy's arms are free, heck, his whole body is free to move. It's the equivalent of walking up to somebody and saying "Hey, I'm going to snap your neck" and then trying to do it by just grabbing at their head and trying this. Nobody is going to let you snap their neck, just like nobody is going to let you do any other technique. Your opponent has a massive amount of room to move, is expecting your attack and has a million ways to escape what you're attempting.
Other thoughtsThese people must be stopped. I can't do it alone. I do this series to expose the errors in the the world of martial arts. I do it by telling you what should be done and very broad concepts of what's being done incorrectly. While this is certainly better than going at it one technique at a time and just saying "that's not effective" without an explanation, I'm still only one man.
