As in bar 7, in the 2nd half of the bar there are no accidentals in A, while the sharps raising all f notes (in different octaves) to f present in GE (→FE,EE,IE) were arbitrarily added while revising this edition. In the main text we provide the A version, adding only a cautionary  to the first of the discussed notes (f2).
