You are correct but to allow this to happen would require an on-board system to allow the train to distinguish between station stops and signal stops.
Why? All other pressure-sealed stock in the UK (that I know of) just releases below 5 km/h. It's quite noticeable on Voyagers where you get outside noise on slowing down.
Though TBH an easy enough fix would be to make the button do something when pressed. On Pendolinos, where you get a delay for the step to deploy, the button flashes when you press it.
A third option would be to start releasing the cam when the doors are released, which would make it a second or two quicker by the time the passenger gets to the button.
