Despite having a decent imagination, I simply cannot visualize the shot that would require having the sticks in the CSC positions. Therefive, I for one am anxious to see what you’re talking about.

Here you go. Granted the sticks were not all the way to the corners in this shot, but you get the idea. I am not saying that I would ever push the sticks all the way to the corners to get certain shots, but the sticks can clearly be pushed into dangerously close positions in the search for uniques shots.
