According to us, omission of the additional quaver stem next to f1 is a result of the Chopin proofreading of FE (→EE), which is indicated by possible traces of correction in print in this place (e.g. a slightly bigger note head of the note). Taking into account the fact that in analogous bar 130 f1 is not extended, one can come to a conclusion that Chopin could have written the fourth stem in the discussed bar by mistake.
