Read an old Flash comic and tell me if you'd understand on your own that Barry constantly vibrates himself to travel through time if there was no exposition window to tell you though. Speedsters are really sneaky with this kinda stuff, and Savitar specifically was a guys specifically designed to be a "Speed Force wizard", with Wally training up in SF knowledge to match him in prowess.
