Hi.

Both \textSpannerDown and the override is applied to the /current/ Voice 
context (which is the unnamed default Voice quietly instantiated inside 
the Staff context). Thus, it is not regarded by the Voice = "1" context 
created afterwards.

Moving the two commands into the Voice = "1" construct works as expected:

\version "2.13.7"

upper = {
  c4 d e  \startTextSpan f % polyphonic
  g4 a b c % monophonic, see below
  b4 \stopTextSpan g e c % polyphonic again
}

lower = {
  c,2 g2 % polyphonic
  s1 % a spacer "disables" this voice tamporarily
  g2 c2 % and here we are again.
}

customOverrides = {
  \textSpannerDown
  \override TextSpanner #'(bound-details left text) = "let ring "
}
