At the beginning of bar 320 and at the end of bar 321, in GE, and on the basis thereof also in EE2, regular bar lines were replaced by double bar lines. It is an arbitrary decision, contrary to Chopin's practices in this respect – he did not use double bar lines automatically when changing time signature or key.
