Watch the Mountain Bossa online guitar lesson by Fareed Haque from 1-2-3 Bossa Nova
Notice that the Abdim7 with 13th added moves to Abm7 then to Gmin7 creating a nice chromatic line in the top voice. Also dig that E triad with an F in the bass(E/F)! That is a hip sound often used by more modern bossa players. E/F is another way of writing Fdim(maj7). This E/F moves beautifully back to F6/9 creating a mysterious leading chord that gets you back home. Ah, those sneaky diminished chords, everywhere you turn there they are, like little green pigs staring back at you - and giggling. Makes me angry just thinking about it!
