The slur of As begins more or less in the middle of the bar, so it can be interpreted as starting from the f1 minim. According to us, a slur of such a range concerned the initial version of the ending of the bar; following its deletion, it is only the a1 crotchet that remained, and the slur inevitably begins from it. A slur starting from the a1 crotchet is also included in GE; however, it is a result of a routine revision, adjusting the notation to certain general notation conventions.
