In FEH, the bottom F minim is crossed out. Like in a few other cases, it is just an additional reminder that the note should not be played and not an actual abandonment of the tie, according to us. Such a transfer of the bass note while preserving a common note is one of the characteristic Chopinesque procedures, c.f. e.g. bars 360-363 i 368-369 as well as the Etude in C Major, Op. 10 No. 1, bars 49-50 and 65-66 or the Fantasy in A Major, Op. 13, bars 114-119.
