Jumping is a hard and straight step to cancel the emergency evacuation. After landing, it will step back again, then jump again, step back again, jump again ... The whole process is well controlled and looks coherent.

Fast attack speed is similar to canceling hard direct attack with fast retreat, and then jumping (small enough) before attacking. At this time, you should land, then rush back, jump, attack, rush back, jump, attack. ....

This operation is too difficult. I estimate that some key software is used in the video, and it is simply not human to press it to that extent.
