Sounds to me like GhostScript is keeping statistics about the character
orientations and the most frequent orientation ends up as that of the
paper (maybe it's only a drawing optimization that unintentionally
bleeds into the result?).

So I suspect that the other page material (tagline?) makes up for
something around 50 characters.

Music engraving by LilyPond 2.17.28—www.lilypond.org

52 characters, minus 4 spaces.  Whoever thought the tagline was
important?
