Utter hogwash. Here's what Paul VI actually said:

“… [the Council] has invested its teachings with the authority of the supreme ordinary magisterium, which ordinary magisterium is so obviously authentic that it must be accepted with docility and sincerity by all the faithful, according to the mind of the Council as expressed in the nature and aims of the individual documents.” 

“We decide moreover that all that has been established synodally is to be religiously observed by all the faithful, for the glory of God and the dignity of the Church… we have approved and established these things, decreeing that the present letters are and remain stable and valid, and are to have legal effectiveness, so that they be disseminated and obtain full and complete effect...”

If it walks like magisterial teaching and quacks like magisterial teaching...
