Corkscrew on Spinning

Wondering if their are any pointers on how to do what I believe to be a one handed corkscrew spin on a spinning pole. I believe this is what Roxy Pink was doing in her video that she submitted for the USPDF video recently. Not sure if the key to holding yourself up is a good grib in your armpit like doing a Teddy or its simply having the strength to keep yourself in place with the one hand/arm that is on the pole.
