First off: Sorry to double post, but I thought this deserved it’s own post.
I figured out how to do the trick.
Try doing a hidemasa hook, but make the string whip way around your NTH, and catch the loop with your TH index finger. Also, when you do the hidemasa hook, throw the yoyo higher than a normal hook. When the loop catches on your finger, if the yoyo was thrown high enough the yoyo will land on the string farthest away from you. Tadaa, you’re in a double or nothing. ;D
Tip:
This trick is easier when you try a double. You naturally throw the yoyo higher in the air, and the string has more momentum to whip around your NTH onto your TH index.
EDIT: It’s not the same trick Jensen did, but it is similar and it still gets you in double or nothing from a whip.
