When interpreted literally, the version of A (→GE1→FE1) is certainly erroneous, although both bars are written in the same way for the second time (bars 462-463). It is proved by the B
-g-d1-f1 chord (and not -e1) in the orchestra, played from the beginning of bar 422, and above all by the flats lowering e3 to e3, which were added in both bars in the proofreading of FE2 (→EE), almost certainly by Chopin. Flats were added also in GE2.
See also bar 423.
