Trouble with Patrick Eiffel Tower

Cool trick… except for those two rolls near the end of the trick. I don’t really know what’s going on and whether I need to curl any fingers in during the rolls. Please help. I know you probably don’t know the trick but it’s super easy to figure out, in some sense. https://youtu.be/i2KDp2LxndM?si=YPJNZmbimmEWuq45
