I've used \etc for rewording the definition:

\version "2.19.82"

whiteout =
-    \tweak layer #0
     \tweak Y-offset #0
     \tweak outside-staff-priority ##f
     -\markup
       \with-color #red % Of course, this should be white, but this is more 
visible.
       \override #'(filled . #t)
       \path #0 \etc

\paper {
  #(set-paper-size "a8")
  system-system-spacing.padding = #-1000 % Makes vertical spacing more even, 
but encourages overlap
}

{
  \repeat volta 2 {
    e1-^ -\whiteout #'(
      (moveto 0.3 -6.2)
      (rcurveto .8 -1.75 .6 -1.75 1.4 0)
      (closepath))
    \break
  }
  \alternative { {
    \once \override Score.VoltaBracket.layer = #-100
    \once \override Score.VoltaBracket.color = #blue
    R1
  } }
}

Well no: systems are drawn sequentially; layering only works within a
single system.
