In PE, the tie sustaining the quaver beginning the sequence of demisemiquavers is absent both here and in analogous bar 74. In spite of that, the sign's oversight – by the engraver or even by Chopin in [A] – seems to be very likely due to the doubtless hold of this note in JC and EF and a structural analogy with bar 62.
