It is difficult to assume that the slurs in the L.H. appearing in GE1 (→FE) could have been added in this form by Chopin – they are contrary to the authentic slur in the R.H., whereas their range overlaps with the beams of the group of quavers. Therefore, it is most probably a revision, which also questions the authenticity of the slurs added in GE1 in the previous two bars. The revisers of EE and GE2 replaced them with a two-bar slur modelled after the slur of the R.H.; it specifies the notation, yet it does not follow from the notation of A.
