To return, drop the segment on your right pointer finger, unwind one string layer with your throw hand and you end up in a classic bind. Pull throw hand and release left segments and celebrate the landing of a cool trick. Cake or Pie works, I personally go with Cheesecake.
The hardest part is getting the slack loop OVER the string segments/AWAY from you so it lands on the far side/away side of the yoyo.
There are no possible knots from this trick, but I do not recommend dropping the segments on your left hand and right at the same time, or your yoyo will snag and hit your fingers. One segment at a time will suffice if you want to simplify things on.
