I believe Jon Woolrich attempted a slow-motion version of the same due to insufficient steering lock on the Hocus Pocus, but it was much less impressive.
I'm not sure what happened to Jochen in the last race of the video. I saw him off his bike on the entrance to the hairpin, so can only assume he got boxed in by other riders, or had a minor mechanical.
