The slur of A, although it ends slightly earlier, is certainly supposed to embrace the entire semiquaver figuration in the L.H. in this bar and this is how it was reproduced in GE2. The division of the slur in GE1 may be a facilitation used by the engraver (in order to avoid a long slur of an atypical shape) or a proofreading, if initially it was only the bottom slur that was printed.
