In reply to tehmarks:
It's pretty much obvious to anybody with photographic experience, that the photo is skewed and he is not climbing a vertical wall (the route from the French side is what, 40-45 degrees at maximum?). It's also quite obvious that he is on some slope, and not on completely flat ground, the original was taken neither horizontally not vertically, it was skewed to start with. If you just rotate the photo 90 degrees to the right (like many people on Twitter did), you would get a skewed photo far from proper horizontal as well. The correct rotation would be around 60 degrees or so. Even when rotated such, it's hard to tell the real slope angle without some investigation that I can't be really bothered to do for just an insignificant twitter photo of some (to me) obscure politician, it's hard to tell a real slope angle from a wide angle photo shot downslope on featureless snow anyway. It could be nearly flat, it could be 30 degrees or anything in between.
Nevertheless, whatever it was:
stupid mistake on the part of the guide holding the camera
phone automatically rotating the photo to vertical (when held mid position between horizontal and vertical orientation, the phone can get confused, which is genuinely easy to do by mistake)
or a poor attempt at grandeur
it's still funny
