I especially like the above line, paraphrased for completeness:
"The new light source with wavelength at 605 nm is not sodium,
although its pattern can be used to determine that the original source
is sodium at 589 nm."

Seto's been told, though he surely does not remember (because today is
Monday) that there is often nothing but a *hole* between the original
source and the diffraction grating that measures the wavelength.
Therefore, Seto is saying that the new light source with wavelength at
605 nm is not sodium, although its pattern can be used to determine
that the source is sodium. Therefore what is not sodium is found to be
sodium.
