It would seem so.
There is an interesting article by John Young (lay theologian from Australia,) entitled, āTHE CHURCHāS MAGISTERIUM.ā Link:

Young says (Emphasis is mine throughout):
Clarifying terms
Now to clarify some terms.
Extraordinary Magisterium refers to a special exercise of their teaching office by either the Pope and bishops together, or the Pope alone, in which a definitive judgment is given. When a General Council pronounces a solemn definition, this is an exercise of the
extraordinary Magisterium. So is an
ex cathedra definition by the Pope: a decision definitively settling the question.
By contrast
ordinary Magisterium refers to the exercise of the teaching office without a solemn definition being given. This is the case with the day-today teaching of bishops in their dioceses, or the greater part-almost the entire part-of the Popes teaching. (Much in these categories, however, has already been defined infallibly.)
The term
ordinary universal Magisterium means an exercise of the Churchās teaching office where there is complete agreement, or fairly close to complete agreement, among the Catholic Bishops of the world that a particular doctrine is certainly true, but without a solemn definition.
The extraordinary Magisterium is infallible. A definition given by a General Council or an
ex cathedra definition by a Pope cannot be erroneous. Likewise,** the ordinary universal Magisterium is infallible**. The fact that the bishops are dispersed throughout the worldā (in the words of Vatican II quoted above) does not make any difference.
What of the ordinary (but not universal) Magisterium? Is it infallible? No, as Vatican II indicates in the quotation above concerning statements that are not ex cathedra.
Does Young have it right?
