Query: Comment on "Nonlocal Coherent Perfect Absorption"   We show that, contrary to what is claimed in Ref. [J. Jeffers, Phys. Rev.
Lett. 123, 143602 (2019)], there is no nonlocal coherent absorption by the two
lossy beam splitters considered in detail in the treatment of the setup
presented in this reference. What happens is a local coherent absorption by the
other two lossy beam splitters of the setup.
