The inner line A, Ab, G in C is the sound of it: the minor iv’s flattened 6th slides down to the 5th of the tonic. It’s heard in ballads and at the ends of bridges. Fm6 has the same notes as Bb9 without its root, so the minor iv and the backdoor bVII7 are often swapped for each other. Practice voicing it with that line on top.
