A basic question on pole splitting - need explanation

hi
i have a basic question on pole splitting.
I have read about miller compensation that it makes dominant pole more dominant and non dominant more non dominant.
My intuition about this is first stage load cap becomes more because of miller effect of 2nd stage and 2nd stage o/p impedance will decrease because of feedback, so first stage o/p pole frequency reduce and second stage o/p pole frequency increase.So if originally first stage o/p is dominant pole is more dominate and then splitting happens but if 2nd stage pole dominates then poles come towards...can any body explain this flaw.....

Thanks,
Rajasekhar.
