In A, the slur over the F-f octave has undoubtedly a motivic meaning, same as the slur in the previous bar. With the change of direction of the stems, in GE the slur was moved under the notes and placed in such a way that it became a tie sustaining the bottom note of the octaves, F. The erroneous version was corrected in FE (→EE) – probably by Chopin – to another version, which, being the latest, we adopt to the main text. One can ponder whether Chopin would change it if GE1 would not have distorted the notation of A (apart from the change of the nature of the slur, the 
sign was overlooked). Anyway, the version of A, certainly authentic, can be taken into consideration when performing the Concerto.
