If wife and husband has two separate email address each belongs to each others personal/private and both is used in Stack.

In such case both becomes as 1 user account under Stack? 
In such case does husband has to plan for divorce to have account seperatly treated in Stack?

    e.g: [email protected], [email protected]
         [email protected], [email protected]

Stack consider all as [email protected] is it not by force pushing the logic to be accepted in reality its nonsense?
