That person will have their legs fucked for life if they crash. Most alpine skis have a mechanism that has to release the ski if there's too much force on it (so as to not break the person's legs), and it seems like it's set wayyyyy to high because they have held up the skiers weight for long enough to take that picture.
There’s different forces required to release forward vs torsion side to side. A DIN 8 setting is typical for a veteran skier this size. I think that’s 180lbs of force per binding of forward lean so you got a lot to work with.
Depending on the terrain an early ski release can be more dangerous than keeping them on. Skiing is risky but that’s part of the fun!
Maybe they're very skilled and managed to get into position in such a way that it didn't trigger the system, which is otherwise normally tuned, but yeah you're most likely correct. Also good to know, more advanced skiers use higher DIN settings (harder to release) to enable them to ski harder on rough terrain without the skis coming off.
From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainly of steel. I aspired to the purity of the blessed machine.
