In A the accents in these bars are longer than in the next ones. The difference was considered insignificant both in FC (→GE) and FE (→EE), which seems to be the right decision, since there is no visible reason why identical pairs of bars (53-54 and 55-56) would be accented differently. However, it could be that Chopin wanted the places to be performed in a more nuanced manner, particularly since b. 53-54 (but not 55-56) were initially provided with a 
hairpin in A, which was eventually crossed out. Actually, one can never rule out a nuanced performance in similar situations, even when the indications do not differ; therefore, we suggest the long accents, interpreted literally, as an alternative version.
