According to us, the earlier pedal release than in similar situations may be a result of Chopin's mistake, who, while introducing the pedalling, most probably in the already finished pitch and rhythm text, only saw the change of the chord and did not check its sound. Therefore, in the main text we suggest a variant solution.
The 
sign in GE1, placed slightly later, is most probably a mistake.
