Need help with Patrick Eiffel Tower Picture trick

Please … I need help. I seem to have several wraps around my TH index during the two roll segments before making the shape after landing on the string. I also don’t know if any pinching is involved during those two quick rolls. Any advice and or top down perspective would be helpful. https://youtu.be/i2KDp2LxndM?si=SF_agwIqVNsm-lxA
