The absence of the 
sign in A (→GE→FE) can be a mere oversight, related to the transition to a new page in A (from bar 119). It is also possible that Chopin omitted this sign due to the use of the so-called diminuendo pedal (gradual release of pedal) – cf. e.g. the 1st mov., bar 300. The sign added in EE is almost certainly inauthentic – cf. authentic pedalling in bars 93-94 and 109-110 (and even 85-86). Taking into account the fact that the chord in the discussed bars, being the base of the passage, does not change after two bars, we deem it to be likely that Chopin had in mind a situation in which the sound would die away longer, sustained with pedal, which is expressed by the addition of a sign suggested by us in bar 120.
