The variable has nothing to do with it.

Here is the difference: The first variant adds the lyrics to \new Staff
\altoOneVoice.  The second variant adds the lyrics to { d'2 ... } even
_before_ \relative is called.  \addlyrics is sort of sticky.  Once the
\addlyrics is sucked _into_ the \relative, it does not have a chance to
combine with \new Staff in a useful manner.  So basically you get

\score {
  <<
     \new Staff \relative << \new Voice="xxx" { d'2 ... cis}
                             \new Lyrics \lyricsto "xxx" ... >>
  >>
}

Or something like that.  Lesson: \addlyrics is for simple cases.
