Ok, that makes sense. So the repeated signal I heard was simply repeated attempts at getting the command through and were being interfered with by the existing FM transmissions. All of the frames I collected would have actually been DUV and not the same as the sounds I heard. Did camera mode ever get activated during that third pass?

What you heard was the command station attempting to send the command to AO-92 to activate the camera.
Unfortunately, there were several stations trying to use the repeater at the time and blocking the commands being sent to AO-92.
When the camera is active, the repeater is not available.

I tried capturing some of the high-speed data from AO-92 today from the final 1750Z pass today when the camera was activated. I believe I had some success, but I am a little confused about what I captured. I did it in two stages using my phone to capture the raw IQ from my SDR during the pass and then playing it back on my computer right after into Foxtelem 108z5. The pass was only 16 degrees at it's peak, but I was able to hear the satellite down to as little as 6 degrees and Foxtelem reported 24 frames successfully decoded.
