But we know that the Sharingan unlocks new abilities at each stage instead
Hell, we discussed a couple times in the Narutoversity\Questions\Rereading topics, all the Sharingan abilities are there from the start the difference is they get better with each tomoe.
The scene linked doesn't work as well without the previous ones, showing Sasuke gettign just a small anticipation of Naruto's movements. the third tomoe marked a BIG improvement but the basis were already there.
Also, Salada is both better trained and more intelligent than Sasuke, so it makes sense she'd be able to use the Sharingan better.
If anything, in the episode she did show having too much stamina(though fainting at the end), though she IS physically stronger than even Chocho
