Why to use min-height with background-size in the same time?

Why Nick used min-height and background-size for background images in the same time? Is not it extra, because when we strictly define the images sizes they can't anyhow change their sizes? Nor above 20 px neither below 20 px

min-height defines the size of the container, not the background. So, the minimun height of the icons will be 20px, and the background is set to 20px so it will cover the min-height.
