In A a number of corrections is visible in these bars. In the part of the R.H. Chopin deleted e3 from the 2nd chord (certainly in bar 48, the traces of changes in bar 49 are less visible) and he changed a2 to b2 in the last chord (in both bars). However, at the time of proofreading FE (→GE,EE), he withdrew from the first of the changes. Cf. hesitation concerning the part of the L.H.
