You can hear the wind ripping in that video. Absolutely a case where there is a huge headwind component (probably just below the stall speed of the aircraft) and all the guy needs to do to get airborne is give it enough power to generate a little prop wash and a small amount of ground speed.

I've actually seen situations where certain airplanes would have a negative ground track at Vso due to high headwind components. You'd be flying backwards, in effect.

It's all about the airspeed.
