Energy entangled photon pairs from parametric down conversion are the considered bipartite quantum system. It is argued that photocount of the energy-analysed photon in one subsystem does not commute with measurements of higher order correlation functions (interferences) in the second subsystem. Both the subsystems are mutually spatially disjoint. Very short measurement sampling times needed to perform the discussed experiment make it rather "gedanken" than real.
