One of the groups appeared to be led by a guide as she short roped her two clients toward the bottom of the buttress. No one was caught out that day but luck might have played a big part in that.
They could have made reasonable decision depending on what they saw actually on the ground, straight lining up a short distance, or picking a line where the snow was thinner and following a line via some rocks, where the snow may have been more stable.
Or, just been lucky!
It's a lottery sometimes, with big stakes, so it's better to try and put more odds in your favour. As someone once explained their reasoning to me, even a moderately poor outcome of say a broken or arm, is that specific route choice or climbing that route really worth the risk of not being able to climb or the next 3-6mths? If not, pick another route or another day.
Corries by their very nature often have faces that point to 3 different aspects, so some will always be much safer than others and if you haven't worked out which one is probably best by the time you have walked into corrie, then perhaps you shouldn't be there.(or at least not without some instruction)
