In this case, if typo one is invoked after a correct one, an URL_MISMATCH_ERR will be thrown in SharedWorker constructor algorithm step 5.4.2.
In the other hand, a 404 will terminate the algorithm and no SharedWorker is created and nothing will be add to global namespace.
I think this example won't be a serious problem anyway, though I'm not sure will this cause other problem or not.

This remind me of something:
From sec4.8.3, SharedWorker constructor algorithm step 5.4.2:
If worker global scope's location attribute represents an absolute URL that is not *exactly equal* to the resulting absolute URL, then throw a URL_MISMATCH_ERR exception and abort all these steps.
Seems the #name part will break this line and throw a URL_MISMATCH_ERR with the duplicated #name2 one.
Shall we ignore minor difference between urls? e.g # fragments?
