Alternatively viewed their qualia are the same to the extent that their situations are the same where there are many many factors that would lead to diverging situations at various levels of organization. ("I" get the impression parts of me experience all kinds of qualia without my noticing, or only barely noticing e.g. when subsystems send signals on the threshold of consciousish awareness. I imagine such subsystems might have qualia for some aspects of the taste of fine wine or pop-country music that "I'm" swamping out with higher level affect, and perhaps hidden qualia for the infinite subtleties of lower level moment-to-moment automatic awareness that my more-conscious mind is numb to but presumably uses as a basis for higher-level qualia like sehnsucht.)
