The version of the majority of the editions resulted from a misinterpretation of the tie to f as a slur referring to the R.H. top voice. The engraver was influenced by the shape of this tie, which, although written clearly at the pitch of f, points upwards in A, as if it belonged to the top voice. This shape was forced by the A layout, in which the parts of both hands are written down on the bottom stave (see the note in the preceding bar). The authentic tie was added in EE2, most probably by analogy with bar 308.
