  It is shown that contrary to claims of Ref. [1] the formulated in the proper
physical variables Low theorem [2] for soft photon emission does not require
any modification. We also reject the criticism in Ref. [1] of the papers [3,4].
At the same time, we identify some inaccuracies in Ref. [3] in the presentation
of the soft-photon theorem for the case of spin-one-half particles. We also
point out shortcomings in consideration of the Low theorem in the classic
textbooks [5,6].
