Right wing stalls during very low speed landing

What happens in this video ?

The Just Superstol aircraft approaches at a very low speed, trying to land on a minimum distance. But the speed is too low, and the right wing stalls. The plane crashed on the runway. Lucky pilot walks away. This happened in Australia in 2015.

The background noise and the flightpath seems to indicate a headwind with some wind gusts that may have contributed to the aircraft's momentary pitch ups prior to the stall/right spin, similar to flaring too high above a runway surface.
