One last thing: an aid to understanding is to
view these horizontal skylines. You can show
them using

#(ly:set-option 'debug-skylines)
\layout {
  \context {
    \Score
    \override PaperColumn.stencil = #ly:separation-item::print
    \override NonMusicalPaperColumn.stencil = #ly:separation-item::print
  }
}
