Thanks for the report.  GIGO is my conclusion.  This is the source:

    <<
      \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }
      \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }
      \new Staff \with { \consists "Volta_engraver" } { c'2 g' e' a' }
      \new Staff { \repeat volta 2 { c'1 } \alternative { c' } }
    >>

The performance length is 4 whole notes, but the third part has only half that. 
 This is not what the image on the LSR means.

There is no \repeat music in the third staff, so why should there be a volta 
bracket?

2.23 is handling this input more correctly.  I don't think this snippet teaches 
anything more than the one entitled "Volta multi staff".
