All those movement abilities are different and work in different ways. You shouldn't clump these techniques together as one. Hirenkyaku is moving fast by riding on the flow of Reishi created below the user's feet. For Bringer Light, speed is achieved through a variety of different uses of Fullbring. By pulling on the soul of the ground beneath their feet, Fullbringers can increase its elasticity, greatly enhancing their jumping ability as a result. In addition, by Fullbringing the air around them, they can accelerate their movements. For one of the other movement abilities, your theory may be correct, but I doubt it.

I copied some words from the Quincy page and Fullbringer page on this website to help with my definitions of Hirenkyaku and Bringer Light, as I was having difficulties properly explaining it myself. If you want to learn more about these abilities, look up the appropriate pages on this Wiki and read to your hearts content.
