Comfort Access with multiple keys?

This is not a question about the virtues of Comfort Access. It is more about a specific behavior with multiple keys present. I did a search a was unable to find a response to my specific query.

Suppose two keys are detected near the car (my wife and I are carrying our keys). What key takes precedence (for the stored settings) when the door is unlocked? The closest key to the handle?

And once inside the car the computer detects two keys. Will it keep moving the seats back and forth and changing all the settings? Or, will it keep the settings of the key that unlocked the car?

Thanks!
