Hiroyuki Suzuki combo help.

Hey ! I recently tried learning this : https://www.youtube.com/watch?v=StQTRY0xOlY
And for me the trick messes up at 5:09,when I drop the string on my TH thumb the strings are twisted a full turn,while his (I think) are only twisted half a turn so when I do the thing at 5:18 it ends up in a kamikaze-ish mount with the yoyo isolated in the twist created earlier.Help !
