This passage is making my brain hurt. You press the button to indicate you need to go up. The problem isn't with the button or the icon, it's with the expectation that the button should assist in helping you navigate the scheduling of the elevator(s). Which it does (to a point). If you're coincidentally on a floor where someone is getting off and you need to go in the opposite direction than the next person in the elevator's queue, the button will not reset. You're still waiting for the elevator. Culturally, people just ask instead of knowing/trying to discern this.
