They are identical in all effects. But we are taught to think in terms of one description because that is perceived to be easier to grasp by text book writers.

That depends on how your perceive shape. If your perception of shape is largely informed by photographs of the outside of the sub, then perhaps it is natural to perceive the shape as having not changed. If you perceive shape as the geometry of that part of the submarine from which water is excluded, then the shape has manifestly changed.
