In case you needed more proof that this scene is a callback to Rebellion, here you go! One Sayaka sword special. :) The head tilt pretty much confirmed it for me, but I appreciate the additional evidence.
Interestingly, although the move itself is the same, there's no exact Rebellion equivalent to this particular shot. In the WnK version, Sayaka has likely just made her move, as evidenced by the clouds behind her, but the Rebellion version doesn't actually show her moving at first, just her sword, and then we see the whole thing from various angles.
This one is the closest that we get to the WnK version:
But regardless of which angle you're looking from, these two moments, parallel as they are, could not be more different. In Rebellion, Sayaka is confident and sure of herself, to the point of cockiness, fully in her element (literally with all the water in this scene). In WnK, Sayaka is half-blind, angry, and desperate for answers. In Rebellion, the question is "which path will Homura choose? does she really know herself?" and here that's Sayaka's question, perhaps with some added confusion over which Homura she's really dealing with here.
I've said this before, but I love the symmetry of the two sides of the highway, and the asymmetry of the half-moon and the shadow on Sayaka's sword. There's a similar shadow there in Rebellion, but here in WnK, it's one more visual indicator of Sayaka's divided situation, which in turn echoes Homura's. Even though their roles have reversed and Homura is in a relative position of power compared to their Rebellion encounter, neither of them fully know themselves. Nor does Madoka, for that matter, but that's a different issue - for Sayaka and Homura, it's the unknown darkness inside themselves that's causing them problems, and which they will (ideally) resolve by the end of the movie.
In case you wanted proof that the yellow bow is another indicator of Sayaka's ignorance of herself along with the bandages, this shot pretty much confirms it. The mixture of red and blue (Law of Cycles + devil) also indicates a blending of opposites, although it doesn't seem like she has much room to maneuver.
We already know that Sayaka succeeds, though not necessarily what the price is for that knowledge will be (can she remain in the world or will she be forced to leave it like she did before?). Homura's situation is more complex, and the movie been deliberately avoiding any mention of the outcome, although my guess it that will somehow involve reducing two Homuras down to one, whether through assimilation or (self-)destruction, with a side order of confusion over which Homura is which.
The highway around Sayaka may be open in this scene, but choice is an illusion; it only goes one way. From here, all paths lead to the Nazukasokotsune, the library of witches, much-needed exposition from Kyubey, and the release of Walpurgisnacht into the world.
