Y'all are going crazy with this.
From talking with him and as he alluded to at the premier, his ender is a line and the line that was included in the film was good ... really good. He did show the crowd an alternate version of that same line and one of the ledge tricks he falls out of (tic-tacs) ... he's trying to get that line.
He's not, as far as I know, trying to get any Suciu grind flip-in or out variation. Interesting thought though.
Hope that helps ...
