(Sorry for the last empty mail, misclicked.)

It's because \bar "||" will not print anything at line-begin.

Though consider the following:

\version "2.19.13"

\new Staff {
  \bar ".|:" \repeat volta 2 { c'1 c'1 }
}

#(define-bar-line "||-r" "||" "||" "||")

\score {
  \new Staff {
    \bar "||-r"
    \repeat volta 2 { c'1 c'1 }
  }

  \layout {
    \context {
      \Score
      startRepeatType = #"||-r"
      endRepeatType = #"||-r"
      %% not needed in the minimal example
      %doubleRepeatType = #"||-r"
    }
  }
}

Cheers,
