The compatibility of the slurring of AI and FE (here and in bars 15-16) is puzzling, as a coincidence seems to be highly unlikely. Chopin could have returned to the original slurring in the base text to FE or at the time of proofreading this edition, so the issue whether the long slur written in A is the expression of Chopin's final intention cannot be conclusively resolved.
