Good to see you are looking at the doc now!
Did you read the nodes previous to that one,
in the same chapter (Buffer-Local Variables)?
I think they answer your questions.

I think node `Creating Buffer-Local' explains this.
If you don't create/set a buffer-local value in
buffer A for a variable then its global, "default"
value applies in buffer A. It's as simple as that.

Check whether (buffer-local-value THE-VAR) is the
same as (default-value THE-VAR).
Again, this is explained in the node that precedes
the node you quoted from.
I suggest starting at the beginning of chapter
Buffer-Local Variables, and reading from there.
