The fact of leading the slur to the beginning of bar 261 is most probably an inaccuracy, which one can easily imagine, being aware of the Chopinesque panache when writing slurs, encountered in numerous autographs. There is no reason for the phrasing to obscure the natural division, marked by the progression's parts and underlined by the additional slurs in the bass in bars 261-264 and  marks. Moving the beginning of the slur to the 2nd quaver in bar 259 is an arbitrary revision of GE3, modelled after the inaccurately reproduced slur in bar 263 in GE1 (→GE2).

In EE1 there is no  to e3. The natural is not indispensable in this case, yet definitely advisable in the face of the  before the 4th semiquaver in the bar at the same pitch. It was added by EE2 (→EE3).
