The FE (→EE1) version resulted from Chopin's correction – the traces of removal of e1 are visible in FE (among the copies presented in our system, most clearly in FE2). In EE2 the note was restored, most probably after comparing it with GE1. In Chopin's pieces there are many examples of chords in the middle or high register with both tripled and quadrupled bass.
