315MHz has a wavelength of about one meter (3 foot). If the gap from opener to the sensor is (for instance) a complete range of wave lengths, and the space through the opener to your car and after that towards the sensor is half a wave duration over a whole number, then the echo will get there from section with the initial signal and terminate it.
