Functionally extraverted function in extraverts makes person more dominating or stabilizing (D and N). Introverted emphasis increases instability and adaptability (C and H) and this is reversed in introverts.


However, if you want to put emphasis on subtypes based on rationality and irrationality it is not the same.
And then there is contact and inert subtypes which might use same two functional notation system.

In essence: two subtype system is a notational mess.
