Simple answer - The same guys who roto-till the reef and/or screw the vis tend to rotate heads up as soon as they slow or stop swimming.
The divers who have trimmed out their weights to they "can" be horizontal at rest do so because they have become more aware of and desire more control of their body in the water. Maybe they don't need to always be horizontal, but it is a choice for them, not gravity.
