In my youth,, soon after my time in the Army,, I did a bit of tree work. And I still do a bit for myself. But I'll be the first one to say that trees can whip your butt.
I wasn't able to view the video,, (all I got was ads,) but I can look at the two pictures & know he got whipped up on.
I also know several tree cutting pros. And a few folks here have met one of them at ROCS shows with me (Tyson!)
Tyson is a seriously top level aerial tree cutter. He can climb,, and work the tree properly. I've helped him several times as his ground man. He likes the fact that I know a LOT about tree cutting,, and we have discussed how to work a tree down safely.
Doing it right is an art which requires top level skills.
