Since the low brake is released, torque from the input shaft drive is not transmitted to the output shaft.

The same as for the "N" position, since the low brake is released, so torque from the input shaft drive is not transmitted to the output shaft.
The parking pawl linked with the selector lever meshes with the parking gear and fastens the output shaft mechanically.
