Clamp Overlap"

What does "Clamp Overlap" do? I googled it but didn't understand

    Clamp Overlap limits the width of each beveled edge so that edges cannot cause overlapping intersections with other geometry. 

    Below I added an edge loop close to the edge of a cube to better see what happens when activating and deactivating clamp overlap with a bevel modifier.
