I can think of only one mitigating factor, I'm not sure we've considered:
What is the terrain like over his exit path? If the runway is on a plateau, with a gully running off at an angle to the centerline, then perhaps he had more clearance than is evident in the videos. Mind you this is my SPECULATION - but if true, maybe this was better planned than we think.
Not that I approve, but then I've also seen some low-down Spit flybys that make me cringe.
