Having just watched the video, I wonder if the airframe was ever under control from the moment power was applied to go around. It does seem to be operating almost off the back end of the drag curve. The final departure appears to occur below the level of the trees, so might have had some “help” from foliage catching the left wing...
The end result reminds me of this:
although in that case they managed to keep the wings level until they hit the trees.
