According to us, the 
hairpins written in AW, together with a tempo appearing in the same place, define a clearly different from the final one concept of return of the leit motif of the Etude. See also bar 51.
It is hard to state whether the hairpins of EE were inaccurately reproduced by the copyist or engraver or whether they were written in a slightly different way by Chopin in the base text to this edition.
