I'm probably wrong here but the turn he makes doesn't seem very balanced from what I can see. It looks like he forgot to use the rudder (like many seem to these days), and it simply rolling the wings, rather lazy for low speed, low alt manovering
Looks impressive though but I'd wager he wasn't fully aware of the wing tip distance. If he does that manouver often enough to "know it" dunt say too much for his employer.
