Sure are some poorly instructed Roman Catholics on this thread.
Yawn...No salvation outside the Catholic Church is what he is saying. No Catholic is obligated to obey every utterance of the Pope.
St. Irenaeus, Against Heresies, ~180 AD
2. Since, however, it would be very tedious, in such a volume as this, to reckon up the successions of all the Churches, we do put to confusion all those who, in whatever manner, whether by an evil self-pleasing, by vainglory, or by blindness and perverse opinion, assemble in unauthorized meetings; [we do this, I say,] by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out] the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its preeminent authority, that is, the faithful everywhere, inasmuch as the tradition has been preserved continuously by those [faithful men] who exist everywhere.
Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.
I see no allowances for what you assert.
You will note Unam came much later than Irenaeus.
But perhaps you're one of the RCs who doesn't believe your current pope, and he is your pope, is legit. Are you one of those?
