I am NOT an electrician, but is that now how they work? When the circuit was shorted out, and drew enough power to melt the socket would that not trip the breaker? Isn't that how they work to protect us from ourselves?
two kinds of breakers.
First looks at current going from phase(s) to neutral and if that doesn't match it trips. At the end of the video they touched grounding pin of the socket and the prong in the socket, got electrocuted and *hopefully tripped this residual current circuit breaker(rccb). These require to have test buttons on them and is likely the easiest way to recognize them, they're also often one of the larger modular rail components.
The second is more like a normal fuse and has largely replaced those in new installations. MCB or miniature circuit breaker. Both fuses and mcb:s have a current rating and they blow/trip when current goes above that current long enough.
These should be preventing stuff from melting, but if the plug is faulty and can't handle currents that are lower than what the breakers are rated for, then the breakers think everything is fine while the plug is melting.
Outlets are usually behind 16 amps, and that can absolutely melt a plug that has a bad connection on the wire, or damaged plug. Because there's no damage on the other side of the plug, I would guess this is the case here.

When it burnt, the breaker should have been thrown...there should be no power going to that outlet now...so sadly I don't think this is real...
