here we're not really adding a gesture, we're just moving it from one token to
another

Good point, I will remove the line.
The flag was flipped to true during the original creation of the token, which
only happens in the other UserGestureIndicator constructor (if I can trust Code
Search). That means the flag was flipped there already.
