In GE (→FE) notes of the R.H. rhythm 
are distributed in such a way that the quaver is aligned with the 6th L.H. note. In the editors' opinion, this probably does not reflect Chopin's intention but we cannot state it definitely without [A]. The rhythmical structure of the bar, different e.g. from that in bars 29-36 & 53-62, as well as the local climax ending in this bar make a possible exception slightly more likely here. In the main text, we apply the regular rhythmic notation, so did EE.
