If memory serves, AC on during recirculation is to dehumidify your interior so that you don't fog up, especially in winter with the heater on. Was the heater on as well? Maybe it's on a timer and will turn off after dehumidifying the air?
It does seem like an odd feature, but it is a life saving one. And I'll bet usage statistics say if you're recirculating, you need the ac on, at least for a bit. The last car I can remember with climate control use to do something like this:
-car on, system waits for heater to warm up
-fans start blowing noticeably when heater has warmed up
-ac turns on when fans spool up
-interior temp climes, at some point AC turns off
-fan spools down when interior temp is agreeable
