If you still have a game "open" when you close XBoard, it will auto-save it. This is not so easy to suppress without running the risk of losing games you would have liked to save. (Like some engine crashing at the point where it is checkmated, thus triggering XBoard to exit.)
I am not sure in which mode you were running, but if you were playing human vs. ICS then a game that is finished on the ICS is still open in XBoard. (I.e. the final position remains displayed, and you could use the < and > buttons to scroll through it.) It is very difficult for XBoard to determine if you want to have that game saved or not, so it has to err on the safe side. After all, even if you saved it before, you could have been editing it (adding comments).
Doesn't the problem go away when you first click "New Game" before closing XBoard?
