An earlier version of slurring linked to the initial rhythm – see the note on rhythm. It is also there that we discuss the mistakes in the reproduction of the slurs of A, committed both in FC (→GE) and FE (→EE).

2 long accents in FCI

No sign in FC (→GE) & FE (→EE)

..

The omission of the  hairpin both in FC (→GE) and FE (→EE) is probably a result of the mark overlapping with the ending of the L.H. slur – each of the arms of the hairpin looks like an attempt to prolong/finish that slur.
Two accents in FCI emphasize the importance of both d2 and the C major chord, but the sense of this transition is revealed only just when they are combined, which Chopin expressed in A by uniting them with one  mark. A comparison of those two marking methods allows us to better understand the sense of  hairpins in similar contexts (Cf. e.g. Prelude in A minor no. 2, bars 15-16). One can also see this change as an analogy to the merged slurs in b. 4-6.
