The 
hairpin in EE is most probably an addition of a revision based on comparison with the analogous motifs in bars 386, 390 and 396. After all, one can ponder whether the mark in FE (→EE) is misplaced in bars 393-394, i.e. instead of in bar 394. However, the shape of the phrase in bars 393-396, different than in the previous four-bar sections, constitutes an argument against such a hypothesis; this phrase is clearly focused on the central e2 note, repeated at the beginning of each of three subsequent bars. The markings in the version of FE emphasise each of the notes: in bar 394 – , in bar 395 – the long accent, in bar 396 – the beginning of the slur.
