I think the main thing with gravity Dust is that it redirects gravity's effects, and that's why those uncontrolled bursts from Ruby's gravity Dust bullets push her away from the burst itself. The burst pushes outward in all directions. If gravity Dust increased gravity's effects, then Ruby using gravity Dust bullets to pogo through the air on Crescent Rose in Heroes and Monsters (they said in the commentary that she was using the gravity bullets) would have achieved the exact opposite effect than what we saw.

So, basically, if you use gravity Dust on something and have the Dust reverse gravity's effect on it, then they'll float into the air. The floating could be more subtle if you don't have the Dust reverse the effect strongly enough to completely fight gravity, thus really just reducing gravity's effect.
