No it'd only link to one of the Commons ones but we're not restricting if this is category or page. (There is likely an item for the page and one for the category about Albert Einstein on Wikipedia)
IMHO, it should be like Yaroslav pointed out (page to page, category to category, but *absolutely not* page to category or viceversa).
Anyway, let's discuss it on Wikidata: https://www.wikidata.org/wiki/Wikidata:Wikimedia_Commons
(should we archive this page and make a new one?)
