A sequence of single SkipEvents like { s1 s1 } will not be compressed.
You need to write { s1*2 }.
See the following tiny examples:

\new Staff <<
  {  s1 s1 }
  {  \compressFullBarRests R1*2 }
>>

\new Staff <<
  \displayMusic {  s1*2 }
  {  \compressFullBarRests R1*2 }
>>


Your example cold read:

\version "2.19.28"

structure = \relative c {
    \compressFullBarRests
    \override MultiMeasureRest.expand-limit = #2
    \override Score.RehearsalMark.self-alignment-X = #LEFT
    \mark "Globally compressed"
    s1*5 \bar "||"
}

globals = #(define-music-function (parser location mus) (ly:music?)
  #{ << \structure \relative { $mus } >> #})

melody = \relative c'' {
    c1 | R1*4 ||
}

melodyGlobal = \globals { \melody }

<<
    \new Staff {
        \melodyGlobal
    }
>>

HTH,
