I think he is just in shock... It happens a lot when people are in shock they do not feel pain or do not understand exactly what happened...
your exactly right.
3 weaks ago i was coming home from lido (outdoor swimming pool) with a few friend, and we went to take a shortcut and i said lets jump over that fence.
they were all like, "nooo! noo!"
and i said omg if u dont jump u are such a pussy. then i climed up it and my sheo got stuck between the rail as soon as i jumped and i fell head first on conrete from 8ft.
it didnt hurt me at all i just got up and i was laughing, then i was like holy shit, cuz i thought i broke my teeth, but im fine
