I think we are talking about \book in general whether in lilypond-book or 
not.

I think he is saying that \book is the top level whether it is explicitly 
stated or not, just as \score is added whether it is explicitly stated or 
not. There are many defaults which are added by Lilypond when not written in 
the file, I think \book is one of them.

For instance, the following two lines generate identical output:

{ a b c d e f }

\book { \score { \context Staff { \clef G \key c \major \time 4/4 a b c d e 
f } } }

and I think all those things are added by default, including \book.

If there is more than one \score in a file, they will all be added to one 
\book, I believe:

\book { \score { ... } \score { ... } ... }

even if the file is written like this:

\score { ... } \score { ... } ...

If instead you explicitly pair a \book with each \score:

\book { \score { ... } } \book { \score { ... } } ...

each \score block will print out in a separate file.
