Yes, it's treated like a regular reservation, because it is! You can go online to the dining reservation section, and under the "My Reservations" tab, enter your room reservation, and it will show up, with your name on it, even though it was made under another member's points. They have control of the room reservation, meaning they can cancel it if they so choose or change the name on the reservation, etc, but you are in control of your dining reservations.
