Yes, that makes it clear.
In v5, AutoSync got some additional features where during the original sync process you can choose which audio tracks from the BWF you want to be part of the new .sync subclip. In your case, you would select A1-A1 (span based selection). You would now end up with a VA1 subclip from the two different sources.
Now, when editing, you only have to deal with the VA1 clip. Do a matchframe to load subclip into source, then turn off V and matchframe again and it will load the original BWF clip with all tracks to use as needed.
Does that get you what you want?
