The key to this trick is to already know how to perform a layout as well as a frontroll to revert.
Cut in with a strong progressive edge. Cut all the way through the wake, as if setting up for a layout. Once you get into the air, throw a front somersault and extend your arms out fully.
When you end up upside down and facing the sky, pull in extremely hard (the load on the line will help to "sling shot" you over) and bring the board over the top of yourself. You'll land in the revert position with the handle tucked into your inside hip.
