What would that have to do with it if it broke an inch above the clamp?
OP--I allow no carbon on my mountain bikes after having seen several bars and seatposts and other carbon bits fail on others' bikes (and having my Trek OCLV bonding fail twice, that bike is ridden very infrequently and carefully now). I don't race (anymore), and want my bike to be able to crash with minimal worry. I know aluminum can break, too, but the one time I messed up an aluminum seatpost it bent and got me home.
