It's an interesting find, although I remember that EpicNameBro didn't take up the japanese description of this item when he made his Izalith lore video, which he most definitely would've done if it was different from the english one. (Granted it was so long ago since I saw it that I'm not even sure if he mentions Ceaseless at all in that video.)

The german version of the game is infamous for having inconsistent translations when compared to the english version. Off the top of my head I can remember two things: The Greatsword of Artorias is called "Finstertöter" or "Darkslayer", if you translate it. The Fang Boar Helm's description says you'll be able to use the helm as a weapon when it's equipped (which is untrue, sadly).

Like you said, it's hard to say which lore is the true one without the japanese version to test it with. However, since some translations (Fang Boar Helm) are simply incorrect, it's probably better to just trust the english one for now.
