In flavor-SU(3) approaches to charmed particle decays to a light vector and a light pseudoscalar particle, this behavior is seen, but does not appear to have a fundamental origin.  Instead, it arises as a result of approximate cancellation of higher-isospin combinations of several types of amplitudes:  color-favored tree, color-suppressed tree, and exchange.
