To me, it sure looks like one of the people on the ground tried to break his fall.
And my guess is also that dog is injured.
This guy was with us for 18 years and has been gone for many years. When he was a puppy we would leave him home but we would leave the second story balcony doorwall cracked a little for fresh air. We came home one day and found him limping around the yard and couldn’t figure out how he got out. He nudged the door open, pushed out the screen and jumped off the balcony. I don’t know the proper bone name but he broke one of his fingers. He never did get any smarter.
He was limping but he was a very happy puppy, in other words, dogs don’t show pain until it’s too late, that dog needs an exam.
