Prior to today the only landings you've seen are Falcon 9, which has to do a "hoverslam" because it can't throttle low enough to actually hover.
Even just one engine in minimum thrust would make the rocket go up when empty.. so the computer lights the engine at the precise right moment so it will have 0 velocity at 0 altitude, then it cuts off the engine. "Hoverslam".
The Starship booster is different, it can actually hover.
