  The authors of arXiv:1501.02093v1 claimed that " ... narrow structure
observed in the excitation function of $\gamma n \to \eta n$ can be reproduced
fully with a particular interference pattern in the $J^{p} = 1/2^-$ partial
wave..." while a narrow structure in Compton scattering off the neutron is
"...a stand-alone observation unrelated to the structure observed in $\gamma n
\to \eta n$...". The source for the second statement may be a simple numerical
error. If so, the interpretation of the narrow structure in $\gamma n \to \eta
n$ as interference effects in the $J^{p} = 1/2^-$-wave and some conclusions
from arXiv:1501.02093v1 are questionable.
