That video is good for the basics.
I would imagine that the beat detection in SMP can probably do something similar. (you should check that out to streamline the workflow)
if it works for the songs you're trying to work on, cool.
If the song has breaks, changes in time signature, Accelerando or Ritardando it is a bit more challenging, but it just means tough songs require manually mapping every bar.

The map become the master timing and all audio or MIDI will follow it for all tracks.

Don't forget when you map the chord changes in ACW you are essentially making a tempo map in BIAB.
