I agree with you.
When it’s bad enough to side step (pretty rare) I will have an ace in my up hill hand and replace it with every step, obviously to do this the shoulders will be facing in the same direction as the skis.
However when side slipping I always aim to keep my upper body facing down the slope, as if poised to make a jump turn. Obviously not completely at 90 degrees to the ski direction but in a downhill direction. I see several advantages. You have a good view down the slope as apose to across it so you can move more quickly as you see what’s coming. You are in a position to more quickly start turning again. I also find it also helps maintain the correct edge angle, pushing the upper body away from the slope as oppose to laying into it which could cause you to lose your edge on steep hard snow.
