In other words if the author of this piece is right then eventually Pope Francis should say or do something that would put himself in direct opposition to established Church teaching. It's an incredible claim when one thinks about it!

Not at all, considering the fact that he has made no secret of his ambition to devolve doctrinal authority to individual bishops' conferences.

"...The Second Vatican Council stated that, like the ancient patriarchal Churches, episcopal conferences are in a position “to contribute in many and fruitful ways to the concrete realization of the collegial spirit”.[36] Yet this desire has not been fully realized, since a juridical status of episcopal conferences which would see them as subjects of specific attributions, including genuine doctrinal authority, has not yet been sufficiently elaborated.[37] Excessive centralization, rather than proving helpful, complicates the Church’s life and her missionary outreach...
