ELI5: How come when someone holds a door open for someone or multiple people they still feel inclined to touch / push on the door even though they aren't doing anything to it and it's already pushed open?

It's a polite gesture to indicate that, should the person holding the door wish to pass on the responsibility, the person who's touched the open door will step in. A non-verbal way to say "Thank you, you're free to walk onward now" should they want to.
