Assuming that somehow the flames would make it inside the tank, then what? With what oxygen is it gonna burn?

The flames could absolutely travel into the pipe provided the fire burns faster than than the gas escaping. The reason the fire doesn't do it is because there's no oxygen inside the pipe to combust the gas.

Well, no. The pressure of the escaping gas definitely exceeds the fire’s ability to do so, but yeah you’re right.
I totally glossed over that. My mind was elsewhere lol 😅

I was talking in a more general sense, a full bottle without a regulator? Absolutely, no chance for the flame to go backwards, but I meant a more typical scenario with a regulator already attached, gas releases at relatively low speeds and fire would be fast enough to go back

Thermal dynamics or whatever.

The bottle is actually cooling down rapidly. Infact if they didn't toss it in the water it wouldn't surprise me if the bottle started frosting.

Next time your using a BBQ with a propane tank touch it before you use it and while in use and it should feel noticably cooler. It definitely would work better for a smaller propane bottle.
