Right. The main error/tenant of V2 is the "doctrine changes with the times". This is why Francis is always yelling at Trads for being "rigid" and not "open to the spirit (of evil)" for change. No pope owns doctrine, as all Divine Truth came from Christ and was handed down by the Apostles. "There's nothing new under the sun" also applies to doctrine, because God doesn't change and neither does Truth. Every doctrine of the New Testament was implicit in the Old Testament, just like every Church doctrine is implicit in either Scripture/Tradition.
On the other hand, the V2 popes do have "personal doctrines" because that's how the false, conciliar church is setup...to constantly change, update and "improve" to (eventually) arrive at the NWO one-world religion.
