It is highly unlikely that the slur added in the stage of proofreading FE (→GE,EE) was supposed to have such a range. According to us, Chopin entered into the proof copy a slur running from the c minim, perhaps inaccurately, which resulted in it starting later in the editions (the slur pointed upwards, just like the one in b. 226-227, which we do not reproduce in our transcriptions). This interpretation is supported by the aforementioned slur in b. 226-227, also added in the stage of proofreading FE.
Such misrepresentations are very frequent in the case of ties, e.g. in the Polonaise in F minor, Op. 44, b. 201-202.
