In A, the 
hairpin is placed closer to the top stave; however, it is under the L.H. slur. Therefore, one can ponder to which part the mark refers, i.e. R.H. or L.H. According to us, the range of the mark, perfectly corresponding to the g1-b
1 step, indicates that the mark applies to the R.H. part. Such ascending motifs, usually within the interval of a second, are often to be found in Chopin's works, while the accompanying marks were often misinterpreted by the engravers of the first editions (just like here), cf., e.g. the Concerto in F minor, Op. 21, II mov., b. 84 or the Prelude in A minor, Op. 28 No. 2, b. 15-16. In FE (→GE,EE) the hairpin was put in a neutral place, i.e. between the right and the left hand, but it was extended to the entire three-note motif.
