According to us, prolonging the b minim with a dot in b. 12 and 36 is not musically justified due to the transfer of that element an octave higher in the last chord and due to the absence of a direct continuation of the tenor sound plane. It is most probably a revision provoked by the two-part notation of the G-b tenth in A1 (→FE→EE), which makes an impression of being metrically incomplete (in GE Chopin already used the one-part notation to write the tenth). Similar differences also appear in analogous b. 68.
