Unless you build only 2-sided boards there has to be prepreg in the board
somewhere so the board can't be built with just laminate.  If your note is
calling out something that doesn't make building the board possible, maybe
it was overlooked.

And if your board is only 2-sided, I can't see that it matters.  The
laminate was made using a foil lamination process.  It's just a matter of
where it occurred.
