Manipulation with ill-defined notions creates an illusion of a simple derivation of the standard phase of neutrino oscillations in hep-ph/0311241 and hep-ph/0312180. Recent remark [1] on a too simple (one page) derivation [2] of the standard formula for neutrino oscillations has been criticized in [3]. Let us remind that the derivation in [2] is based on ”the plane wave approach, in which the m...
