If you're basing this on Weiss's ability to create a pushing or pulling force, I'm pretty sure you're wrong. Though, I can see how you'd think that. Pyrrha actually says it in episode 14. Weiss' Ability to push or pull things is her Semblance. Her glyphs allow her to create these platforms bearing her symbol. Also, in the "White" trailer, I believe white Dust is used to deliver a powerful finishing blow to the Guard Armor. Although I could be wrong about how white Dust works, I'm fairly sure her glyphs are what allow Weiss to push or pull things. Good question, though.
