On the mass neutrino phase calculations along both the particle geodesic line and the photon null line, there exists a double counting error--factor of 2 when comparing the geodesic phase with the null phase. For the mass neutrino propagation in the flat spacetime, we study the neutrino interference phase calculation in the Minkowski diagram and find that the double counting effect originates from despising the velocity difference between two mass neutrinos. Moreover, we compare the phase calculations among the same energy description, the same momentum description and same velocity description by means of the Minkowski diagram, and obtain the practical equivalence of these three descriptions. Further, in the curved spacetime, we also prove the existence of the double counting of the geodesic phase to the null phase.
