No. That’s not what the means.

It means that, if a Pope contradicts what the Church has alway taught, then he is teaching error.

There’s no “personal interpretation” involved. Either the current Pope is teaching what the Church has always taught, or he is contradicting what the Church has always taught.

(I am not speaking here of matters like global warming, on which Bergoglio just teaches lies, and the Church has no teaching. I’m talking about the teaching of Jesus wherein he defined that marriage is indissoluble.)

Unless you pony up for the annulment??

And therein lies the rub. "What the Church has always taught" encompasses a huge body of practice, pronouncements, documents, etc. A Catholic must, by necessity, employ personal interpretation regarding what (or who) is authoritative and what (who) isn't. A Catholic, looking at AL, must by necessity employ personal interpretation and come to a conclusion.
