The L.H. slurs added in bars 1-2, 2-3 in FE are almost certainly inauthentic. They were probably added due to the change of the layout: in the notation of A (→FC→GE), the R.H. part is situated on the bottom stave together with the L.H., as a result of which the slur over the notes naturally concerns both parts. In FE (→EE) the R.H. part was moved to the upper stave; hence the articulation and phrasing of the L.H. was no longer obvious. It could have been noticed by Chopin himself; however, it is difficult to assume that he could have added a slur suggesting a different phrasing of the L.H. An identical addition in GE1, which was not proofread by Chopin, perfectly illustrates the attitude of the engravers or revisers (in GE1 and EE in bars 1-2 it was also the R.H. slur that was adjusted to the L.H. slur, contrary to the Stichvorlagen).
