It understands the bounce and where it is in your club. Most amateur golfers have no idea where the bounce is on their club or how it works. Do a few rehearsals before the shot to feel the bounce every time. Understanding it and how it will work best for you will help you enjoy golf a lot more. And play better.
Drills for this are getting an old golf club and going to a hard path like a road with a ping pong ball first, then golf ball, and start hitting the ball to get your timing right. Start hitting shots with the backspin method.
