I really don't understand what this is saying, could someone elaborate PLEASE?

If the batter hits an out-of-the-park home run, it is a dead ball with all four bases awarded. If the outfielder throws his glove to knock the home run down, or a fan reaches over the outfield fence to keep the ball on the field, it is still a dead ball with all four bases awarded.
