Breaking the slur between these bars is a characteristic inaccuracy of the engraver of GE1 (after all, the two-bar slur in bars 125-126 is already a result of proofreading – the remaining elements of original slurs show that each of these bars was most probably embraced with a separate slur). The continuous, four-bar slur written in A was restored in GE2. See also bars 128-129.
