In the main text we provide the A tie, clearly at the pitch of c2. The fact that in GE (→FE,IE) it was assigned to the middle notes of the chords (f2-e
2), hence turning it into a slur, was an arbitrary decision by the engraver of GE. Moving the slur to the pitch of c2 in EE, hence restoring it to its initial form, a tie, was also arbitrary – the publisher did not have access to A, yet he interfered with the notation of the slurs/ties between the pairs of the L.H. chords in this place by adding slurs/ties in the next bar, in which Chopin did not write them.
