On the contrary, if there are simultaneous turns(which you have if there are two companions beside each other), Its useful in multiplayer if you know that your companion is preparing a spell, or a dash, or a skill... before moving yourself. And if they have a "channeling" animation you know he/she`s going to do something.
I think that´s the case. When Lae`zel is about to make a dash or a superiority manoeuvre she changes the stance before moving and attacking.
I think it's not but it's something you noticed way less with dash and such skills than spells (and it's sometimes hard to see it because we can't choose where the camera is focused on)
Pretty sure Lae´`zel have a Dragonball channeling stance before dashing in 27.38 and another one before "Action surge" afterwards.
