One can judge the wingtip clearence from the cockpit, that's probably why he didn't hit the ground, but one can easily be mistaken...
I realy thing he had a bad performance, to do that manouver he should have pulled before he rolled, and then bleed off some energy during the roll, that's the beautiful and safe way to do it. But he had no excess of energy, rolled first and was hanging on the engines during the turn. It wasn't beautiful, and it was dangerous, and I don't believe it went as trained in the sim. It's a pitty, he is capable of a better display, I don't know what got into him.
Since this is a site for rumors:
The acft was called in by maintenance for a rudder inspection, as result of the dutch roll in another of the low passes, as it as suffered abrupt rudder deflections. This story still has a lot to be told...
