Clarification sought re usage of "than either ... or" in comparative context (e.g. PT44.S3.G3)

I've read through the comments and still don't really quite get it. Yes, I see people referencing to https://7sage.com/lesson/why-is-or-so-confusing/, but that lesson barely touches on the nuances of "than either ... or" in a comparative context. Quite a few posters made inquiries on this, but there wasn't really any explanation given.

Other than just taking this particular usage as axiomatic truth and accept that "than either ... or" in a comparative context (e.g. the parmigiano cheese is more expensive than either the cheddar cheese or the provolone cheese) necessarily means "and", how else can I digest all this? I'm curious, b/c the inference gleaned from that one stylistic choice has a big effect on the game (probably shaving at least 2 minutes for a particular question, if not helping to resolve the game board significantly).

I should also mention that had the phrasing been along the lines of "more expensive than either of the other two cheeses" (as opposed to "better than either the cheddar or the provolone"), that would have also removed the ambiguity.

Thanks in advance

Bumping this in the hope of receiving feedback.

I should note that the phrasing in PT44.S3.G3 is different from the following in Q2 of PT5.S2.G1, which reads

"If John passes all his courses and receives a higher grade in geology than in either language".

Here, it's more than clear that the referent of either is necessarily both languages (Russian and Italian) as opposed to possibility of one but not the other.
