GE1 ends a page on bar 71, and the slur reaches the end of that bar. This may suggest a possible continuation of the slur in the next bar or a tenuto ending of the slur. In bar 72 a new slur starts from the beginning of the bar in support of the latter, and that is how we reproduce it in our system. In any case this amounts to the engraver's inaccuracy, amended in GE2.
