How do they show that? All I see is an aircraft in an unusual attitude impacting the ground violently. This could have come about for many reasons: disorientation, flight control failure (rudder hardover, etc.), improper inputs plus anything else you can think of...
If you look at the 3D plot of the flight path (assuming that data is reliable, which I believe it is) the go-around seemed to be going smoothly until it suddenly didn't.
Latest information is that a/c staled and dived over left wing, falling from 900m at 400 kmh speed.
