Comment on Consequences of the single-pair measurement of the Bell parameter

Genovese and Piacentini [Phys.Rev.A 111, 022204 (2025)] claim that in a recent experiment[S.Virzì et al., Quantum Sci. Technol. 9, 045027 (2024)] the Bell parameter was measured on a single pair of photons thus it challenges several conclusions and discussions on the meaning of Bell inequalities as well as certain QM interpretations. We explain that the parameter measured in Virzi et al. experiment it is not the Bell parameter S which was discussed and estimated in many loophole free tests. Therefore, this experiment neither challenges our understanding of Bell Tests nor allows having doubts about Bohr complementarity and contextuality.
