I find it odd that they did not reply to you in Mode A. Given that the warnings about excessive power can lead to random mode switching on AO-7 stretch back 37 years, one can only conclude that they wanted the satellite to be in Mode A.

I was listening to AO-7 in Mode B as it rose at 2153Z.
At 2158Z, AO-7 suddenly switched from Mode B to Mode A.
At the time of the switch, there were two stations using excessive power (badly FMing) on the bird. Not sure if that was a coincidence or not.
Called CQ on Mode A in both CW and SSB with no response.
