Of course not! I've also heard that studies had shown that synaptic connections between the two hemispheres were more numerous in left-handed people's brains than in right-handed people's ones (thus making communications between the two hemispheres more important than in right-handed brains). In other words, brains of left-handed people would be *less* lateralised than brains of right-handed people (which in my opinion is compatible with what you are saying). So left-handedness is not associated really with a swap of lateralisation but with a lessening of said lateralisation.
