The successful explanation of fermion mixing and of the fermion mass hierarchy by the dualized standard model (DSM) scheme is based on the premise of a fermion mass matrix rotating in generation space with changing scales at a certain speed, which could in principle lead to a sizable flavor violation observable in high sensitivity experiments such as BaBar. However, a full perturbative calculation to one-loop order reported here shows that this kinematical, flavor-violating effect of a rotating-mass matrix is off-set in the DSM by parallel effects from rotating-wave functions and vertices, giving in the end only very small flavor violations which are unlikely to be detectable by present experiments. The result means that at least for the present the DSM scheme has survived yet another threat to its validity, which has indeed been its most stringent and dangerous to date. It also provides some clarification of certain concepts connected with the rotating mass matrix which had previously been found puzzling.
