Carport Question

If you have an extra long carport that can hold two or even three cars, but it is only one car length wide. Would that be considered a one car carport or a two car carport? I was talking to an appraiser that said if each car cannot move independently of the other car moving, it should be considered as if it is only a single lane. Is this true or would it be a two car carport? I added a photo for easy reference. It would be the one in the middle where the car is parked behind the other vehicle.
