Why is it confusing?  Whether bishop, archbishop or cardinal, there is no change in the 'power' of the ordinary in his diocese.  You seem to hold on to the theory that a cardinal has more power than a bishop.  A cardinal's  only additional 'power' is to elect the next pope.  Francis knows that and hence, people like you seem to struggle with his understanding of church law. You obviously don't make many pars on the course!!
