Consideration is given to the consequences of giving up the chirality condition and the assumptions about the nature of the dynamics in the Hubbard model used by Lindner and Fedyanin [1]. A self-consistent pair of soliton solutions is found for the case when the electron-phonon interaction is switched off ($I=0$) and their possible modifications for $I\ne0$ are discussed.
