Without knowing anything about it, I believe "&in" is used when the game istelf feeds you an object as a string. In a collide callback there is no place in the script where you tell call the callback with an object. It just takes any object that collides and passes the naming criteria. So the "&in" part probably means that you're expecting any object.
Technically you do say what you expect in void OnStart, but the function doesn't know that. It just knows that there is a parent and a child, and both could be many different objects.
