Sorry, Donny, no... Recorded audio does NOT follow your chords!
It will (on the BK-9) however follow your tempo and key. So if he slowed the arranger down, or transposed to a different key, sure, it would all stay in sync.
If you notice, the lines the guitar player laid down ALREADY had the changes in them. It's a fairly simple piece, just the four chords, mostly. The guitarist plays a four bar loop that covers them. Then you play the chords for the arranger that follows them.
That open funk guitar style of playing can sit well over a variety of changes...
