Faldage, on the other hand, think of this example:
My mother, Mrs Tipping, Ayn Rand, and the Pope.
Regardless of whether the OC is used, ambiguity would remain on whether the second item was an added detail about the first, or whether the first and second were separate items.
For mine, the bottom line is that we need more punctuation marks. I’ll write to my local member immediately.
Actually, maybe we just need to use parentheses more often. Some people tut-tut, pooh-pooh, or even pish-tush, but I think this is a perfect case where you need brackets in prose.
My mother (Mrs Tipping), Ayn Rand and the Pope.
Or for the Oxfordians:
My mother (Mrs Tipping), Ayn Rand, and the Pope.
