After preparing As, Chopin decided to forgo the note played on the 3rd crotchet. Therefore, he had to choose whether the chord on the 2nd crotchet was to correspond to the chord in the previous or in the next bar (in terms of position). Initially, he opted for g-d
1-f1, only later, while proofreading FE1, he changed it to f-g-d1, which is proven by the remaining elements of proofreading visible in FES. The version of GE (g-d1-f1) proves that the German edition was based on a proof copy of FE1 from before this proofreading. The four-note chord in bar 53 combines the advantages of both versions, hence it seems that it could be used in bar 13 as well.
