So then the question is, how do you separate the intent from the act? That is, "I do not intend to do what the Church does (provide the sacrament)...but I still do what the Church does (say the sacramental form with proper matter)."
What is an example of a priest who does NOT intend to do what the Church does, but still does it? I'm still not grasping the anathema of Alexander vs the very "low bar" of sacramental intent.

Someone who simulates a sacrament uses the right matter and form while interiorly withholding, refusing, or otherwise failing to intend to do what the Church does.

There are few to no normal situations under which this would occur. But a prelate who is sleep-walking would definitely lack the requisite intention. Or, suppose a bishop was held at gunpoint to ordain a man (whom he was known to not want to ordain) . The bishop might interiorly and explicitly, in his mind, will to stimulate the sacrament. I think if I saw a sacrament administered under duress I would hold it doubtful.

There is no reason to run around doubting sacramental intention. De Lugo and Cupertino have never suggested otherwise in their excellent posts here.
