Abstract

Potoček and Ferenczi [Phys. Rev. A 92, 023829 (2015)PLRAAN1050-294710.1103/PhysRevA.92.023829] provided an analysis of the experimental evidence obtained by Danan et al. [Phys. Rev. Lett. 111, 240402 (2013)10.1103/PhysRevLett.111.240402] for the surprising behavior of photons passing through an interferometer, in particular, motion on disconnected paths. Potoček and Ferenczi reproduced the results of the experiment, but when analyzing its modification, they claimed that the reasoning of Danan et al., which led to disconnected paths, is erroneous. It is argued here that the criticism of Potoček and Ferenczi is unfounded.
