How much roll rate will you get from asymetrically deployed flaps? 100 degrees per second, maybe more. So what difference will it make if you are already at 15 or 20 degrees of bank before moving the flaps? And the chance that your bank counters the flap asymmetry is 50 percent anyway, gving you one split second more to move them back...
