What's preventing the LT buckling on the 10m glass fins of Apple store 5th Avenue ?

I was thinking about this recently, I see no lateral bracings on the glass fins. My hypothesis is that the glass façade itself is acting as a lateral bracing for the glass fins. Is my hypothesis correct? Can someone decode the secret behind this structure for the rest of us?

Yes the glazing braces the fins.

Wouldn't like to be the window cleaner on that building.

the glass fin is slender, but what forces does it really withstand?

the fin is only braced on on edge, the other edge is free to warp.

my guess would be, if there was a seriously big and wet pile of snow on the roof, and you ran a stringline down the inner edge of one of those fins, the glass wouldnt be plumb/true along the entire length
