We consider the missing slurs over the descending octave motifs to be an inaccuracy – cf. the slurs concerning the previous two motifs. The omission of 2 other L.H. slurs in bars 129-131 justifies the introduction of respective additions directly into the main text.
The GE version is most probably a mistake or revision.
