In A, the pair of dynamic hairpins was written as close as possible to the top voice so that it was clear that it concerned this very voice; the slightly shortened 
mark is a result of lack of space. For reasons of clarity, in the main text we move the marks over the stave. In GE (→FE,FESB) the mark was prolonged, which could be considered acceptable; however, as a consequence, the mark seems to concern the R.H. bottom voice too, which is exactly what Chopin wanted to avoid in A. In the version of EE, the original notation is distorted even more (due to lack of access to A).
