SSAO simulates shadows by making a black glow around objects depending on the depth difference to the background.
Here's a video that shows it pretty well

The difference between medium and high is just the resolution (high = screen resolution, medium = 1/4 screen resolution) so at medium it's a bit blockier but it's hardly noticeable.
