I have not heard that before. Is it not true that both cormorant AND anhingas
have to dry their wings after feeding and bathing due to the fact that their
feathers are not water-repellent as both genuses lack the oil glands other
birds use while preening to help waterproof their feathers?

While I would not dispute that some thermoregulating was also going on--or at
least warming up the wing muscles, why would it not apply to both birds?
