The Short Answer
Actually it's because of how the vehicle is built. It has to do with aerodynamics. Having a vertical back window and "flat" read end of the vehicle crates a pocket of low pressure because of the slipstream around the vehicle so any moisture sprayed up by the rear wheels is pulled into the vacuum and splattered against the rear window.
