Separate L.H. slurs in b. 250-252 and 258-260 are an arbitrary revision of GE2. One reason for this might be the changes to the original layout performed in that edition, in particular moving the R.H. part fragments written down by Chopin on the bottom stave together with the L.H. part to the top stave. Due to the separation of the parts of both hands, it becomes less intuitive that the slur over the R.H. part applies to both hands (we do not reproduce the layout of GE2 in our transcriptions).
