The slur in A, despite its reaching quite far to the left towards the 1st crotchet, definitely begins from embracing the chord on the 2nd crotchet. Still, in GE (→FE→EE) the slur begins on the 1st crotchet. The result of corrections halfway through bar 30 is not obvious at the first glance and GE1 (→FE→EE) do not end the slur at that point. A more detailed analysis of the notation reveals that Chopin divided the original slur, which was probably already noticed in GE2 (→GE3).
