I agree; I think that when she glides, she is using a lower level of her Semblance. During the fight between Glynda and Cinder, not all of their attacks formed glyphs, only the really powerful ones. Weiss may be the same, as her blue-glyph acts very much like an acceleration platform. Her lunge could just be the base level. However it does seem weird she wouldn't use it without her sword if all it required is a hand motion. Maybe the reason Weiss has a sword filled with Dust in the first place is because she can't properly focus her abilities, but that is a completely other topic.
