Comment #3 on issue 2735 by address@hidden: Clarify use of page  
breaking paper variables
http://code.google.com/p/lilypond/issues/detail?id=2735

I've now found an example, see below.  With the default value of
blank-last-page-force this typesets on 4 pages, i.e. on the front
and back of 2 double-sided pages.  With blank-last-page-force set
to 50 (just uncomment that line) it is typeset on 5 pages, i.e.
on the front and back of 2 double-sided pages and the front of the
last, third, page, with the back of the third page black.

So, blank-last-page-force seems to do exactly what it says: it
forces a blank last page as the back of the last double-sided
page.

Here's the example file I used:


\paper {
  indent= 0
  page-breaking = #ly:page-turn-breaking
%  blank-last-page-force = 50
}

\score {
  {
    \repeat unfold 7 {
      \repeat unfold 50 { a4 a a a }
      R1*4
    }
  }
  \layout {
    \context {
      \Staff
      \consists Page_turn_engraver
    }
  }
}
