I thought of hula hula is just the mobility of the HIP. like dancing a hula hula.

The axis tilt is caused by the BUMP of your hip either parallel to the delivery lines or flight path depending on your swing type, with a Stationary Head. To ready a right shoulder support as per 2H and transfer of momentum.

SO You don't really have to think of clearing or tilting the hip as per hula hula . It happens. The reason its there is because you dont want to RESTRICT your hips. and it reacts to the swing.
