The slur of As, written over the 3rd version of these bars and probably applying also to the 4th version, is most probably only an origin of a slur leading to bar 97.
As far as the notation of AI is concerned, it is difficult to regard the absence of slurs in bar 91 as Chopin's intention, in particular considering the fact that the ending of the slur in bar 90, the last one in the line of the text, clearly suggests its continuation. According to us, Chopin most probably wanted to repeat the slurring of analogous bar 75. In the main text, we adopt the continuous slur of A and the editions.
