Dude. Ruby said that glass is not Cinder's Semblance. That was the writers' way of telling us "That's not Cinder's Semblance." Cinder just uses Dust to create the glass. In Beginning of the End, she kicked up dirt and melted the dirt with the Dust in her sleeves.

I'm not even sure what you're trying to prove here, since it's pretty obvious that he already had his prosthetic legs when he fought in Beginning of the End, considerng we saw them. However, we didn't see him fight with them until after he had joined Cinder.
