  I critically discuss two of the potential inconsistencies pointed out in the
recent manuscript by Epelbaum, Gasparyan, Gegelia and Meissner, published in
Eur. Phys.J. A54, 186 (2018). The potential inconsistencies are: (i) a possible
mismatch between the $\hbar$ expansion of the scattering amplitude and
renormalization, (ii) an impossibility of "non-perturbative renormalization" to
deal with repulsive singular interactions. The conclusion is that these
inconsistencies do not happen.
