>shouldn't logically

Magic rules don't need to be logical. You could easily say
>"the magic held in a ring is unique and more sensitive to similar magic comapred to otehr magic items, and will interfere with each other if the rings are worn on the same hand.

because attunement isn't that logical, either.

>some magic items are so powerful that you can only use their power after performing a ritual and you can only use a handful of these items.
>ring of three wishes.
