There is nothing strange going on around the 20 second mark. The sun is very low and the wing is almost aligned to the position of the sun. You can also see the left tip is bended upwards, so the guy is clearly running around that tip. But because the lens is zoomed in it's a little hard to see the actual depth.

His "shadow" (CG, no doubt) is on the front of the wing, while he is still "behind" the wing.
