The issue is that Magnus was not tied to Nirn in any way: he designed it, looked upon what he and Lorkhan had done, decided he wanted nothing more to do with it, and left Mundus for Aetherius. He did not give any part of himself in its Creation as the Aedra did, as he was simply the architect, not the builder, and left almost as soon as he had completed his work. The "Eye of Magnus" was so named by the College due to the fact that it was an immensely powerful artifact that radiated magicka: there is nothing to suggest that it is even remotely related to Magnus at all.
