Amongst other things washout (or a lesser angle of attack than the rest of the wing - about 3 degrees in the 360 compared to the flap in the non-reflexed or down 7 degree position) stops the tips from stalling before more inboard sections of the wing, theoretically making it less likely to snap one way or the other at the stall. This would suggest that as soon as the speed comes down flaps to the non-reflexed position would be mandatory. I am not able to speak with experience with this but that is what theory would suggest.
