Correct me if Im wrong however this is the only conifer that sheds it's leaves.. umm err needles in winter?
.. well at least the ones that I know of any how.
You are not far wrong. I can only list 9 conifer species that are deciduous. 3 of them are larches - Larix kaempferi (Japanese Larch), Larix decidua (European Larch), Larix laracina (?) Hackimoto has already mentioned the Taxodioum species - Taxodium distichum (Swamp cypress), Taxodium ascendens (pond cypress), Taxodium mucronatum (montuzema cypress) is deciduous in cold areas,
Then there is Glyptostrobus pensillis (Chinese Swamp Cypress).
Metasequoia glyptostrobiodes (Dawn Redwood) is also a deciduous conifer and, believe it or not
Gingko biloba - though it appears to have broad leaves is actually a conifer and it loses its leaves too.
