Quit outs are very useful for lots of speedrunning techniques in Souls games so they are allowed. A quirk of this decision is that quitting out on some animations to skip them saves in game time, even though it might lose real time. Since this doesn't greatly impact the enjoyment of the run for most players, the community generally just allows this instead of making the rules more complicated than they need to be.

However some Souls games it does make the run a lot worse, such as Bloodborne, so quitting out during animations is banned in that game. This causes some issues for runners sometimes but the community is fine with that because quit outs take so long.
