Lilypond docs do not seem to explain any way to print the key signature
accidentals on different lines than standard, except for this crazy method
where the alterations count for just one octave.

<speculation>
There was no way to alter the printing of the key signature, 
someone needed to do so, found the data structure for the local key 
signature that tracks transient accidentals, including octave, used
that as a way to serve his need, and posted to the snippets list.
<end speculation>

It would be better to use standard key signatures with custom scales
  wholetone = #`((0 . ,NATURAL) (1 . ,NATURAL) (2 . ,NATURAL)
      (3 . ,SHARP) (-3 . ,NATURAL) (-2 . ,FLAT) (-1 . ,FLAT) )
  { \key d\wholetone  bes1 }
and adapt the print routine
  key-signature-interface::alteration-position
to allow for more flexible printing.
