I've noticed most pro players and high rank players always run slightly backwards when they're about to pop Hunter's Fury, can someone explain why they do this and what it does? Many thanks.

Valorant has been spiking randomly recently. Im psure its only val cuz any other game I play this doesnt happen. https://preview.redd.it/swoflv3r3dva1.png?width=177&format=png&auto=webp&v=enabled&s=7cdd5d660bb928556aaa1346bc4c68b245aebf3d
