Ignoring any shift in meaning for now, I can see how "complementOf" makes sense if Bobs are 'characterizations' - as you say the characterizations can be complementary. But if Bob is an entity as we currently have agreement on, complement seems to be the wrong word - there aren't complementary entities involved. "ComplementaryCharacterizationOf' would bring back the meaning as you've described above, but that gets long relative to ViewOf ...
