  In the year 2013, Danan et al. published a paper [Phys. Rev. Lett. 111,
240402 (2013)] demonstrating a counterintuitive behavior of photons in nested
Mach-Zehnder interferometers. The authors then proposed an explanation based on
the two-state vector formalism. This experiment and the authors' explanation
raised a vivid debate within the scientific community. In this paper, we
contribute to the ongoing debate by presenting an alternative experimental
implementation of the Danan et al. scheme. We show that no counterintuitive
behavior is observed when performing direct spectrally-resolved detection.
