In A it is unclear what type of accents Chopin meant on the 4th beat of these bars. According to us, the use of long accents is more likely, which is indicated by both the shape of the sign in bar 4 and the placement of the sign in bar 5: this kind of short, yet shifted signs are sometimes to be found in Chopin's autographs, cf. e.g. Ap in the Etude in A minor, Op. 10 No. 2, bar 22, 27-29, 32, 45-46. In the editions the accents were reproduced as short; moreover, they were moved between the parts of both hands – the latter could have been indicated by Chopin in the proofreading of GE1.
