Not exactly. I think it's more like only 1-2 nomination slots. Unless the academies nominate people for the VP slot that they don't intend to offer an appointment to.
Additionally, even if you already have a nomination from another source, that MOC slate could be filled by another candidate ahead of you who receives an appointment, making the VP nomination a useful backup for all applicants.
Someone gets it, so check that box when possible. It looks like that ship has sailed, so I wouldn't sweat it at this point.
