We interpret the mark in FE as long accent. This is how it was also interpreted in EE, in which the accent was slightly moved in the direction of the part of the R.H., which, according to us, probably better reproduces Chopin's original notation. In GE1 the sign was interpreted as diminuendo hairpins, while in GE2 it was additionally extended, so it embraces the entire group of semiquavers.
