The shorter R.H. slurs in bar 2 and 4 resulted from arbitrary decisions by the GE engraver (→FE,EE,IE), who standardised the slurs concerning the left- and right-hand motifs, which seems justified. However, the A notation is exceptionally precise and consistent, hence we keep it in the main text, although in this context both versions indicate the same performance, according to us.
