I'll rephrase the question ('hum bucking' coil)

My previous thread got off track (I apologize), so perhaps if I rephrase the question we can stay on track. Referring to figure 42 in the attached UTC catalog sheet, observe the 'hum bucking' coil and associated 1 uFd cap. Notice that the rectifier feeds pin 2 and that the cap connects to pin 1. What is the theory behind this configuration? How does it work/sound? It must not have been a huge commercial success, since only a few UTC chokes offered this configuration.
