The clear and coherent slurring of A is certainly the only authentic one. Initially, the engraver of GE1 replaced the Chopin slurs with whole-bar ones (same as one bar earlier); it was in the proofreading only that the right-hand ending of the slur beginning in bar 208 was drawn to bar 209. At the same time, the slur in bar 207 is so inaccurate that in FE it was led further on, until the minim in bar 208. As a result, in FE both slurs coincide on this chord, which EE interpreted arbitrarily as a combination of slurs.
