In this paper I have returned to the coordinate representation of Coulomb propagator and wave function significantly simplified thanks to spiral choice of Dirac matrices (see Appendix). The series in Zα appeared as hypergeometric functions, division to soft and hard photons and their sewing became superfluous etc. The nonrelativistic part of shift is shown completely due to contribution of only one partial wave P 1/2 of propagator.
