It could have served that purpose, but why did they evolved different design in neck-structure, one for the lower plants and the other for the higher trees and where is the sail often accompaniing for heat-gain and heat-loss? These necks probably served as giant bill-boards during mating, when you have such long things sticking out of your body, why not use it to impress other members of your genus? Alright, this does not corrolate with the relatively short neck in Dicraeosaurus and Amargasaurus, of which the latter was for defensive purposes, but this was compensated with the high cervicals, enlarging the space they could use for showing of.
