I won't presume that you clicked the links, so here's an analogy.
You preheat your oven to 450 degrees and yet when you put your hands in you don't get burned. Why? Because air has very low heat conductivity. If you touch the metal grate though, which has high conductivity, OUCH!
Coals have low heat conductivity so if you move fast, it will not burn you.
I have no doubt that it takes some considerable mental trust to try it. But it has nothing to do with mind over matter. It's simply physics.
I don't suppose that you will be convinced by this. That's okay. I just wouldn't waste too much time or money on somebody who claims that it is anything other than a technique that exploits particular facts of nature which are true for anybody no matter their mental state, other than overcoming the inherent fear to try it.
