The natural raising d2 to d2, added – most probably by Chopin – in the proofreading of FE3 (→FE4) is most likely a correction of a mistake and not a new version of this detail. The bottom notes of the dyads (and in the chords also the middle ones), unless they are an octave doubling of the top voice, always belong to the components of a current chord in the entire section comprising bars 17-36.
