Exactly. But the problem is that it doesn't always put the tick mark back in the box, so the user doesn't know it has defaulted back to AI control. There have also been a number of reports of the game ignoring the first clearance of the box, so it has to be cleared, re-ticked and then re-cleared to take effect; although I don't remember ever having personally experienced that bug.
