Because it actually isn't _just_ showing the desktop. its a plasma specific 
action. You get full screen OVERLAY (as was mentioned), of ALL of your 
plasmoids. Which are likely re positioned and possibly resized to all fit. It 
should even include all of the plasmoids from all virtual desktops and 
screens. All neatly arranged in a possibly translucent overlay.
