The added slur in the L.H. is obviously musically justified. However, in the main text we keep the original notation, since Chopin used both notations in similar contexts – with a slur only over the R.H., valid by default also for the L.H., or with separate slurs for both hands. Both EE and GE3 added a slur corresponding to the slur in the R.H. – in EE to the end of bar 121, and in GE3 to e3. The slur in EE begins only just in bar 121 (on a new line); however, its beginning points to continuation from the previous bar.
