In the editors' opinion, the placement of accents in GE does not necessarily reflect the notation of [A]. If Chopin wrote accents between the staves (like in the preceding bar) then the signs could overlap with the slur and what in turn could prompt the engraver to shift them below the lower staff. Accents could also be placed on the lower staff below b, as that type of notation is present in Chopin’s autographs. For that reason we suggest placing accents in a way that most probably is in keeping with Chopin's script or equivalent to it.
Lack of signs in FE (→EE) is certainly a mistake.
