That voicing? He plays the 4 inversions of it with the diminished a half step prior (half step in the melody) that is the base of what Barry Harris and Randy Vincent teach. The dim/6 scale. I tuned out after a while so I dunno if he actually explained the concept of the finished passing chords and chord tones. Also if you look at the first couple of bars of Joe Pass playing Stella the F#m7b5 and Dm7 are m11b5 and m11 respectively...so at the very least in addition to "that" m7 voicing it takes the m6 and m7b5 voicings and a handful of dom7 voicings. But in essence that IS all it takes to start.
