I've rewatched the video several times now, and I actually think the POV guy is at fault.
For me, the video is misleading. You think that the trail continues on straight, which makes you think the girl has skied into the man's path. But watch it again.
If you look closely from 0:25 onward, you can just see mounds of snow on the right getting closer to the POV man. Also, right at 0:31, you can see a big rock (or some other large, dark object) on the right. To me, that indicates the right edge of the trail is not far away just before the man makes a big right turn. The lack of trees makes it seem the trail goes straight, but it has actually turned to the left. (This is quite common in the Alps, which is why whiteout conditions are dangerous; it's easy to go off the trail when it has taken a turn but you think it keeps going straight.)
Also, just before impact, you can see the girl's skis are not on edge and are pointed almost directly at the red fences at the bottom of the slope, in line with the other tracks in the snow. Lastly, you have to remember that the POV man just made a big turn, so even though it appears the girl is cutting across him, it's actually the man who is cutting across the hill. His POV is not the same angle as the fall line
To me, that indicates that the girl was skiing relatively straight down the fall line over near the edge of the trail. Then, instead of starting with a left turn, where there is more open space, the man makes a big turn towards the right, even though he is already not far from the right edge of the trail.
Any farther to the right, and she would have no room to make right turns. So, I can't really see how she could overtake any farther from the man without going off the trail. Also, even after the guy made his turn, the girl wasn't going all that much faster than him, so it's not like she was flying past him at crazy speeds. I think she got squeezed into a tight spot with nowhere to go but past in a straight line.
The force of impact didn't seem all that big, given that the girl didn't come close to falling, so she probably thought it was no big deal. But, she still should have looked back to see if everything was ok.
