I know this from biology!!!

The leaves grow like that to stop as little water escaping as possible. Something to do with them growing when it's cold.

probably also an icr/snow thing - needles wont have to hold a big burden of snow, and if they do then their relative strength would be more than that of flexible high SA normla leaves

Yup, I would say the same. To avoid water escaping because of less leaf surface area.
