It would be great if the author said that. She doesn’t say that, though. She says, “For instance, what is at the beginning of the original signal will be at the end of the reflected signal — a situation akin to looking at yourself in a mirror and seeing the back of your head.”
Which is a surprising thing for a person with a PhD in nanophotonics to say.
