The second listed supply is not needed because it is also the input supply of the first supply and therefore will always be on at the same time. In retrospect the panel probably doesn't qualify as simple since it apparently does need both of these supplies, even if in the case of the Medcom Wide it isn't necessary to explicitly hook them up.
