if you care about this guide still: you could add another note on dash a realignment. if your off your line you can dash a in the direction of the target after the side step.
seems redundant but it's for new people right?
aa after sidestep you still need to point in which direction you want to aa if you 22as then you will be facing 8 so you need to hit 6aa. I don't even think it cancels the sidestep it just aa after it's over. I still wouldn't recommend aa since it just adds to more button presses and you could easily get 2 more hits anywhere else in your combo.
