Again, I'll reiterate - scrolling is frictionless.
Secondly, even if I am changing tasks, that doesn't mean ruining the state I leave in it is an acceptable side effect. Your browser history isn't corrupted when you leave Firefox.
That's a stretch. Ruining? You can still scroll down. The affordances of these actions means, at most, you're going to have to touch the screen once more to "get back to where you were." If you're using an application that doesn't provide the menu after a short swipe, that's a fair enough issue to raise with the implementation of the pattern, not with the pattern itself. It doesn't surprise me that you encountered it on FF Mobile, because FF has a longstanding tradition of ripping things off from successful UIs and getting them wholly wrong in their implementations.
I can hardly believe the question needs to be asked, but it would be more appropriate to say "what logical sense does it make to bind scrolling to menu actions?" (The answer is none, which is why we didn't have this feature until now, and won't have it for long.)
That's your opinion. Unfortunately for you in this case, it's wrong. Try it on iOS Chrome / Android Chrome or Safari and see how it's done properly before making a sweeping judgment on the interaction pattern itself.
