In the main text, according to the entries written by Chopin himself in FEcor and Ap, we give the long accent mark over the 2nd crotchet in the L.H. In FE (→GE,EE) it was given a form of a 
hairpin on the 1st beat of the bar, which totally changed its meaning. In the next proofreading Chopin brought back the stress on the E-e octave by adding 
this time. According to us, it was an ad hoc intervention, forced with an erroneous interpretation of the intended by Chopin accent's mark, which is more compatible with the whole of dynamic markings of the Etude (a comparison of Ap with the final version shows that while preparing the Etude for printing, Chopin made a careful selection of the marks; he would often discard marks, among others; cf., e.g., bar 4).
