It's because of targeting multiple objects - sometimes when you do a window, you may want to do several overlapping windows to help you build up your final selection.

If previously selected objects inside the window became unselected, it would interfere with this - objects in the areas intersected by multiple windows would keep flipping their selection state instead of all staying selected.

This is probably not too hard, I can give it a try when I get back.
