Could easily have ended badly. 
Looks like he’s trying to emulate FPS Russia.

Re: WTF
People don't seem to understand just how dangerous oxygen is.
It may make up 20.9% of the atmosphere and we need it to live but it is dangerous, especially when under pressure.
I used to be technician on oxygen breathing and mixing systems and we called oxygen the princess of gases, treat it right and it is good, treat it badly and you are in for a world of hurt.
The explosion in the video is likely have been caused by a process called adiabatic compression. I have seen it first hand twice. Oxygen is prone to it and then provides an atmosphere that helps the surrounding materials oxidise and burn more readily.
In one case I saw it completely melt the brass fittings on a fill hose because the oxygen was fed under too much pressure and it hit a closed valve (causing adiabatic compression). The closed valve had the wrong o-ring and seat materials for oxygen use, so bang, molten brass flying across the workshop...
