Ladder Escape Help!

I need help with the mount! I get something really weird. After I bring the yoyo behind the strings it tels me to curl my finger in the out and all that. I do that and then it says to bring my thumb and find a certain spot and bring it up. I don’t know where that is all i see is one spot so i put my thumb their and it totally looks wrong. I don’t know how to do it! I looked at everynsingle video and none of them help!

Did you look at this one?

You just have to open up the loop on your throwhand pointer with your thumb after you curl your pointer in.
