Both slurs in these bars are written in A inaccurately – their endings do not reach the crotchets in bars 459 and 461, although they point to them quite clearly. A comparison with analogous bars proves that they are almost certainly to be interpreted considering not only their position in relation to the bar lines. GE1 (→FE→EE) interpreted only the second of them in this way; moreover, both start from the 1st beat in bars 458 and 459, which is a mistake. The division of the slur in bar 460 is an arbitrary change introduced in GE2 (just like in the three previous analogous places).
