yeah I think it originated with thought to temperature and heat rising etc...but with a decent flow and totally air bled I don't think it would matter that much...the only other reason I can think of is the outlet from the engine is at the top and the inlet is at the bottom...it's cheaper for the factory to use shorter hoses !
