That makes sense and seems to explain things. Perhaps you can comment on one other thing that has me puzzled. Since we do not have 1090 cabability I did not expect to see airline targets with a callsign label attached. I was seeing labeled airline traffic on approach today. I assume the ADS-R you mention rebroadcasts the entire info tag with the traffic. Is that correct?
