There is no before the top most note of the chord in bar 79 in A (→GE1op), necessary before g1 due to the notation in the four-flat key signature. The sign was added in the remaining GE. In bar 80, Chopin did not write a before the lowest note of the last chord in A. The sign, although only cautionary in this context, is undoubtedly justified in this place and it was added in GE.
