  In a recent paper, Kurzynski et al. present a gedanken experiment that, they
claim, violates the Klyachko-Can-Binicioglu-Shumovsky (KCBS) noncontextuality
(NC) inequality beyond its maximum quantum value, and a similar experiment
that, they claim, violates Specker's NC inequality, which is not violated by
quantum mechanics. We argue that these claims are baseless, since these
experiments do not satisfy the conditions required for any observation of
contextuality through the experimental violation of a NC inequality. Moreover,
the physical events in the experiments of Kurzynski et al. do not have the
relationships of exclusivity which the authors assume they have.
