That's correct and still has nothing to do with an autolock function as stated by the OP. There is NO function for the F10 that will lock unlocked doors when leaving the vehicle. There is no reason to leave a window open for a valet "in case the doors lock" because there is no way for them to lock by themselves.

I'm assuming this feature (this also happens on my wife's Murano) is there to protect you by re-locking the car if you accidently hit the unlock or you get side-tracked after you have hit the unlock button and don't actually go into the car.
