Based on the description this is a function baked into the system. If you run on recirc for a certain period of time, it will automatically switch the blend door to outside air. I think they incorporated this after the explorer issue with exhaust getting pulled in through some hatch vents and continually recirculating high CO in the cabins. The fix was replacing the vents, exhaust tip redesign and software update to the HVAC module that forced it out of recirc after a set time.
