No.
Church bulletins do not, and cannot define which Mass “counts” for each day. Canon law does that.
You are correct, but what I am saying is that they have a statement as to which Masses are intended to fulfill the Sunday obligation. This is partly because many of the churches are not having all of the regular Sunday Mass schedules, and there is a lot of confusion among the parishioners.
I would presume in making their statment, they have consulted canon law and are properly guiding people so they attend the right Mass.
Some of the parishes have gone so far as to hand out little postcards with this information.
