The range of the 
mark in A may give rise to doubts, since its arms are of different length. The engravers took into account the bottom, longer arm and assumed that the mark reaches the last small crotchet. It does not seem to be an accurate interpretation of Chopin's intention, since such long crescendo cannot be simultaneously combined with smorz. - -. The editors of mUltimate Chopin assume the top arm of the mark to be reliable, written first, and this is how they reproduce this hairpin both in the transcription of A and in the main text.
(Minor inaccuracies in the reproduction of the A hairpins by the editions are also to be seen in the case of the previous marks in this bar.)
