I’m reminded of the the time, during the Protestant reformation, when the Lutherans approached Constantinople for support. Instead they got a bunch of platitudes. Interpreting them positively, the Protestants pushed and pushed to get the Patriarch to issue something definitive. Finally they got him cornered and he told them he did not agree with them, but liked the idea of friendship between their people, but if they kept pushing, Friendship would be impossible.
I think this is what Catholics are coming up against. They put more traction on those discussions than we do, and when they hear positive feedback, there is an assumption that it means there is agreement.
If someone seems to be saying two things, pay attention to what they say to their own in group, and interpret what they say to you in that light. Also accept that positions change, and what someone said 10 years ago, is not binding on them now.
