Ah, but she used the Dust arrows in those explosions, rather than her own power. After she stole Amber's powers, she created the explosions herself. Since Maiden abilities are mimic Dust manipulation, I'd argue that's why Ruby and Glynda seemed stumped. And why they wouldn't recognize Cinder having a Maiden's ability. It'd just look like average Dust manipulation.

If someone can grab screenshots of the very first fight Cinder was in, I'd appreciate it.
