I wonder if it has to do with ease of compositing multiple models. If you have three X-Wing models in the same shot you can have one in focus, with the others a little blurry and if the front one passes in front of the others perhaps it makes the compositing easier since instead of cutting two models separately and trying to make them look correct as they pass in front of the camera, you just cut them out together.
