The shorter 
marking in GE must have been an arbitrary decision by the engraver, who adjusted the sign to the bar. By contrast, the FE hairpin, of the same range as in GE, can be coming from Chopin, who would add some performance markings twice – both to A after [FC] had been finished, and to [FC] or proofs of FE1. This is also supported by the presence of a 
hairpin in FE at the beginning of bar 265 – with longer hairpin this sign would be contradictory.
As in analogous bars 94 and 98, the in FE, certainly authentic, can be considered an alternative or an addition to the accent on e
2-e3 written in A – see note to bar 265.
