No way. If Neo stayed in the carriage until after Raven left, why didn't she finish off Yang? If she can essentially turn invisible, why doesn't she incorporate that into her fighting style? Why wasn't there the sound of her boots hitting the floor of the carriage as she landed?

It's an interesting idea, but this seems like little more than a minor animation error to me.
