Years ago, I saw Rick Baldassin RPT demonstrate that a bowed string will have little or no Inharmonicity while the same string struck will exhibit the characteristic Inharmonicity that is expected.  Perhaps the "ghosting" technique mimics what a bow would do. I usually hear lots of "jingling" sounds, that is, faint, rapid beating when tuning the lowest strings.  I assume these are the highest of the coincident partials.  Because they are the lowest strings, the highest of the coincident partials are still within the audible range while among the highest strings, only the lower sets of partials may be audible. One way or the other, I think a different set of partials becomes more prominent when playing the interval versus using the ghosting technique.  But still, *why* only with this one example?  It's an interesting puzzle.
