No slur in A

The slur of GE1 (literal reading)

A probable interpretation of the slur of GE1 (→FEEE, →GE2GE3)

..

A has no slur in the 2nd volta of bar 60. The slur added in GE1 – perhaps by Chopin himself – is not clear as far as its starting point is concerned. It may be interpreted either as a continuation or as a freshly started slur. It was read as the latter in FE (→EE), as well as GE2 (→GE3).
