I think they are completely different. I think the way the author calls it "reading in stereo" is a very good picture. It's not a footnote or a liner note that explains the meaning of a word. Those live outside the text. It _is_ the word and it lives within the text. It's the inherent meaning of the characters painted on to another word.
