In A, the L.H. slurs, written with a flourish, clearly encompass the groups of five repeated chords. In FE (→GE,EE), they begin earlier, which resulted from the routine approach of the engraver of FE, who considered whole-bar slurs to be most likely. The fact that the actual notation of A was interpreted quite liberally is evidenced by the ending of the slur over b. 32, which, in spite of the fact that in A it reaches b. 33, ends on the last crotchet in b. 32 in FE (and rightly so in this case).
