They don't necessarily know for sure it has been removed from the previous machine, which is why you have to do phone activation if that same computer's MAC/config has not shown up with another key since you activated, or a certain period of time has passed.
What you are doing with the robocall is trading a series of numbers which deactivate your key on the old machine and activates it on the new machine, thus keeping it on only one machine at a time.
