I've noticed that at high AOA the Super Hornet deflects its ailerons and stabilators in opposite directions. The following image shows the effect. The ailerons and rudders are positioned in the orthodox manner, as the F/A-18F executes a roll to the right, however the stabliators are deflected in way that traditionally supports a left hand roll:

I would have expected stab deflection opposing aileron deflection to cancel both roll and yaw tendencies produced by those surfaces, leaving the rudder as the only effective aerodynamic control. I guess I'm trying to say,
'why aren't the stabs and ailerons left at their neutral, zero deflection angles'?. Thanks
