What follows is my opinion only.
It looks as if the voice context for the second \addlyrics is lost
after the first \addlyrics. This does not surprise me.
The behaviour is not more weird than the code itself.  \addlirycs is
not intented do be used this way, that's why you obtain an unexpected
result.

  { music } \addlyrics { lyrics }

is a short for

<< \newStaff { \new Voice=name {music} } \new Lyrics \lyricsto name
\lyricmode { lyrics } >>

It is a simultaneous construct, but you don't use <<>> and therefore
is not clear what you try to achieve by just putting more music after
an addlyrics.

This is what you can do depending on what you want:
Do you want your music and lyrics to be simultaneous?  use <<\new
Staff {music} \addlyrics {lyrics}\new Staff {music} \addlyrics
{lyrics}>> .
Do you want your music to be sequential and your lyrics to be
simultaneous? first concatenate music in a single voice, then use
addlyrics twice.
Do you want it all to be sequential? first concatenate music and
lyrics, then use addlyrics once.
