They wouldn't. That's why authors shouldn't set it more than once.

They're not. Authors "should avoid setting the autofocus attribute on 
multiple enabled elements in a document" means that it is wrong to do so.

Well, it depends on the UA, but it is quite possible for the UA to have a 
concept of "focussed control" per-frame, and then the concept of a 
focussed frame, in which case this works fine.

I agree it should just be one-per-page. The spec already disallows more 
than one per page.

Sorry it took so long to reply.
