In what sense? I can come up with numerous examples in which it still
wouldn't match. In fact, in *most* cases it still wouldn't match. I
can't however figure out what particular example would make them
match.

Not really. Consider a library libfoo that is linked with libbar not
because it uses symbols from libbar, but because libbar used to be
part of its API before the code was split into a separate library.
Dropping libbar from libfoo's DT_NEEDED would break programs linked
with libfoo, and even force libfoo to change its SONAME.
