          Note: If you include ‘\relative’ inside a ‘\repeat’ without
          explicitly instantiating the ‘Voice’ context, extra (unwanted)
          staves will appear.  See *note (lilypond-usage)An extra staff
          appears::.


Not really related as far as I can see.  There is no \relative here, and
at the problematic moment, a Timing context most certainly exists and is
visible, and the current context is already instantiated as a Voice
context.  You can put \new Voice or \new Staff around the whole repeat
or its body without change.
