Just like in bars 422-423, the flats lowering e3 to e3 and the cautionary before e2 in the L.H. in bar 463 prove that the version of A (→GE→FE1), interpreted literally, is erroneous. In EE, a respective is only in bar 463 (together with a before e2), which is probably a result of an oversight of the sign in bar 462.
