Oh, that's not shift, that is offset. I have honestly never ever used that. On the other hand, i use shift in VrayCamera and Camera Correction modifier on non-Vray cameras quite often. And i bet i am not the only one. Workflows of Modo and 3ds Max community probably differ a bit, and i believe if Modo guys had an one-click solution to make their vertical lines aligned, many of them would not resist the temptation. Even if it may not be technically right solution ;)
