Yes, meant to say damper goes to recirc when fan is off, rest remains, believe what you want to believe, as always. Cars are not airtight as most people think.

".. damper goes to recirc.."
I would more readily believe "..damper goes to fresh..".
Cars do not need to be very airtight for rising cabin humidity to be a problem during coolish or cold climate(***) operations. So the default damper position should ALWAYS be FRESH.
*** Climatic periods, basically, when the only usefulness for the A/C is for dehumification.
