Oops, I said it wrong. I meant internal rotation of the humerus. Pronation, of course occurs below the elbow, and would not help to achieve a vertical or near vertical forearm, which would require the axis of the elbow "hinge" to be rotated to as close to the horizontal line (when in swimming position) as possible.
