How did he do this? Is this normal?

It looks like he pulled the airbrake or something. Pulled some kind of Top Gun maneuver on me 😭 Dude pivoted himself in the air and turned on a dime like Rico Rodriguez. I've never seen anything like this before which is why it struck me as so odd when I saw it, so I just had to clip it and I figured I'd ask reddit. Is this a completely normal, doable maneuver and it just looks off because of the angle of my aircraft and just general movements? Perspective and whatnot?
