Because if you just remove the fuse, you will be still pumping gas into the engine while it is turning over, which is not a good idea; if you disable the fuel system and vent off the residual pressure, you will prevent gas washing over the cylinder walls and into the oil sump, which is a primary cause of bore scoring.
