A Corkscrew is a Btwist from a Moonkick approach.
As the base leg pivots into the Moonkick, the hands are brought back towards the hips. Once the base leg is blocked in, the trail leg kicks across and upwards (much like kicking a soccer/football). As this happens, the practitioner jumps off of his base leg and wraps his arms across his body in the same direction as he kicked his trail leg. While wrapping, the legs are brought in tightly and the head turns in the appropriate direction to aid the twist. After 360° of rotation, the trick is landed in the same way as a Btwist would be.
Like the Btwist, the Corkscrew is supposed to have flatspin of 180°.
The Corkscrew has evolved somewhat over time into the move we are familiar with today. If you watched older videos of Daniel Sterling or Anthony Atkins you will see that the Corkscrew was done from standing or moving straight forward. It wasn't until people starting spinning or using the J-step that the Corkscrew started to have the 180 flat spin. The flat spin also creates momentum that makes performing swing thru combos from a Corkscrew much easier.
There is much controversy over how much rotation there actually is in a corkscrew. The flatspin in a corkscrew makes it appear to have 540 degrees of rotation, however as the trick is simply an off-axis gainer full, it only has 360 degrees of twist.
Uninverting the trick does not magically add 180 degrees of rotation to it.
