+1.Is it one or the other? I'm not sure I understand what you are asking.
+1.
I thought the goal was to be skeletally stacked with upper body/lower body separation if you want to ski efficiently.
....Stacked = the body upper and lower and through the hips are aligned in same direction of skis.
Separation = the chest/shoulders/upper body always down the fall line while the legs separate
Ok one place it seems there is confusion is that when I say separation I don't mean legs separated far apart from each other. I meant legs separation from the upper body as for aligning with the skis legas hips upper body all facing the same direction vs when letting the legs rotate while keeping the upper body down the fall line.You can be stacked or upper/lower separated without separating your legs. This is pretty much the premise of modern skis to be able to quickly shift between these modes depending on how you want to address the terrain.
These two pics are in sequence on the same run.

A preference for a certain degree of stacked skiing, which in my view means more equally two footed weighting without you leg separation to weight the outside ski, should align with a preference for loose tails (splay, etc.) that can be kicked out quickly from a stacked position, along with generally wider skis.
The question in my mind isn’t really stacked vs. separated, but the extent to which you are looking to create edge angle and turn shape. Some skis are vastly more flexible in working with you here than others and this is a big reason why the ski width debate is always so out of context.
I skied this line more stacked as speed increased, bouncing lightly into and out of the turns. A lot of separation and edge angle would have been too slow for the snow depth, density, and pitch - and not anywhere near as fun. This is the same terrain as the first two pics.

Not sure I get you. That first vid there certainly is little to no separation as for rotation of upper/lower body vs lower. Its all aligned. Its not the upper body remaining facing the fall line while rotating the lower underneath like you can see him doing in the two in the other vids.Yeah, your terminology is messed up. That first vid you posted above ^, the stacked one, that guy has upper and lower body separation in his turns. You never want to ski like this ==> Goose stated: " Stacked = the body upper and lower and through the hips are aligned in same direction of skis."
Ok, seems to be some confusion. Perhaps the term/s are too generalized, not completely correct.
The way I understand the differences...
....Stacked = the body upper and lower and through the hips are aligned in same direction of skis.
Separation = the chest/shoulders/upper body always down the fall line while the legs separate.
