I'd rather use

\tagGroup alto,non-alto

\lyricmode {
  \tag alto { on -- ly al -- to }
  \tag non-alto { ev’ -- ry -- one ex -- cept al -- to }
}

\keepWithTag alto ...
\keepWithTag non-alto ...

But one would need to look at the rest to see whether this kind of tag
group would end up problematic.
