The answer is: They are not. Whosoever told you that is off his meds. Alternatively, in some special applications there may be a reason for it. Many DC systems use a common ground where the loads are encased in the ground (like starter motors). Thus all breakers are positive, but some don't. If the loads don't care about polarity and the positive and ground are not common (like with a metal chassis), positive and negative is irrelevant.
