A possibility that Chopin added such slurs in the L.H. in bar 256 in the proofreading of GE1 has to be firmly rejected. However, he could have added there the same slur as in the R.H., which was implemented by the engraver in a distorted form. It allows to confer a certain likeliness of authenticity on the slur of GE2. In the main text, we stick to the notation of A, since the need to perform the part of the L.H. with the same phrasing and articulation as in the R.H. is obvious here. The slurs of EE, being a completed version of the erroneous slurs of GE1 (→FE), are certainly arbitrary.
