Apparently it does >electronic shuttering instead of mechanical shuttering. > Exactly - I use Silent Mode on my D4 during live performances where camera noise would be a distraction. It is absolutely silent - I have to chimp to reassure myself that I am actually capturing images. Silent Mode produces a 1920x1280 jpeg (no RAW in Silent Mode) image - same size image as my old D1H produced - so it is not for times when you need a lot of pixels.
