It is the top arm of the 
hairpin in AF, probably written first, that we consider to be reliable, since it emphasises the accenting nature of this mark. In FE (based on AF) the mark begins slightly later, which allows us to assume that it could have also been in GE that the engraver began the hairpin later in order to avoid an intersection with the bottom voice stem (two bars later the mark is present in GE only, hence without [AG] one cannot say whether Chopin repeated this notation there).
