Mechanical stability. When soldered down with four leads the part is can't move in any direction. The shorted pins makes the pinout slightly more versatile when routing a PCB. When introducing 2 extra pins for mechanical stability is probably cheaper (and more rugged) to build shorted pins than to add unconnected pins.

What is a 4 wire switch?
It has four wires coming out of the back. For Single-Pole Wiring (a single switch controls the light or outlet) it's easy: The A wire (black) connects to the hot (black) wire from the power source. The B wire (blue) connects to the other wire from the load. The C wire (red) is not used and is capped with a wire nut.22 Jun 2017
