It is simply a calculation of principal axes where atoms are mass-weighted points, see:
I doubt someone would publish a paper about such a fundamental calculation, so although I did not read the J Mol Graph paper, it is likely to be a different method.
The person who wrote the "measure inertia" code is away currently, but if there is anything else to say, he may send another reply later.
