Leon, It seems that reflections off glass or some such are going to happen no matter which way you have the PF setting. I think a better way to think about it is that the popup will not contribute significantly to the illumination. Remember that the wireless system is using light from the flash to communicate, so the flash is firing, just not at full strength. For most subjects, the reflection of light from the popup is not going to be material. One thing you could try is to cover the popup with red cellophane (couple of layers) to weaken the flash even further or put a deflector in front of it to put the light upwards.
Anyway, I have a feeling that the body is behaving correctly. The popup has to fire to tell the others to fire and then it has to fire again to tell the others to stop firing. The PF switch would just alter the intensity of the popup, not eliminate it.
