In A the 
mark practically reaches the last semiquaver in the bar and this is how it was reproduced in the majority of the remaining sources. According to us, in this context, Chopin could have meant only a long accent, as he clearly wrote 4 times in the next bar. EE considered – also probably on the basis of the marks in the following bar – that it should be an accent, which was given separately for the right and the left hands. See also the note in b. 33.
