KAKG,
I wish I could have asked! But Radar was pretty busy at the time, and when I did ask my colleague "what does that mean?" he wasn't sure either, and he DOES have a PPL. I decided on the LSB because it might have had a bad outcome. I just didn't know, I played safe.
The pilot was able to maintain altitude and speed, and went visual and landed safely. He did not at any stage declare an emergency on R/T.
