Then I have to ask, what is the difference between

Text = \context Lyrics {
   \lyricsto "NumberOne" { Cee }
   \lyricsto "NumberTwo" { Ray }
}

TextTwo = \context Lyrics \lyricmode {
   \set associatedVoice = #"NumberOne" { Cee4 }
   \set associatedVoice = #"NumberTwo" { Ray4 }
}

I was under the impression that {} is a single musical expression,  
music expressions may be nested, and that music expressions enclosed  
in {} are sequential. So then, why does the example using \set  
associatedVoice work and the one using \lyricsto not? In fact, if
\lyrics "voice context" {}
is equivalent to
\lyricmode { \set associatedVoice =#"voice context" }
wouldn't my example be expanded as

Text = \context Lyrics {
        \lyricmode {
                \set associatedVoice =#"NumberOne { Cee4 }
        }
        \lyricmode {
                \set associatedVoice = #"NumberTwo" {Ray4}
        }
}
(Which also compiles as expected.)

Also, since \set associatedVoice needs to have durations explicitly  
stated, they can't possibly be the same.
