While its spoiler ...

Charlemagne who joined force with Hakuno is fictional Charlemagne from Twelve Paladins of Charlemagne. Meanwhile Karl is the true, real life Charlemagne.

Its similar to Vlad that Vlad (EXTRA) is the closest to 'real' Vlad while Vlad Apocrypha is Vlad after his reputation tainted through fictional works of Dracula. Not really confusing; one can be summoned under multiple facets depends on said Servants reputation that their original appearance / mindframe might warped in process.

Hans, Edison, Nightingale, Salieri ... FGO have good number of them.
