No worries Josh, happy to elaborate. Answers inline below.

Well, it depends - it could be the author(s) of the Software, or if a party accepting contributions has a specific scope in mind, they can provide a LARGER_WORKS.TXT file with that content for someone who is going to be developing or agreeing to a contribution.

A downstream fork cannot modify the file and expect this to be legally effective any more than they could simply edit the license text - the authors of the Software are making a grant of specific scope, and a downstream recipient cannot expand that scope.

Sure, the first example that I can think of would be Oracle Java, where someone is developing a JSR reference implementation and this therefore allows us to ship that code in either OpenJDK or the proprietary licensed Java packages. Another example from my own world would be MySQL, which likewise has versions shipping under both GPLv2 and proprietary licenses.

That's a good one. This is just another form of the downstream distributor choosing to sublicense the code on other terms (just like they could under GPL or Apache or a proprietary license), and would therefore mean the person receiving the Software would not get the broader patent grant from the downstream distributor. They also might not know they could actually get a broader grant from the original authors without looking, but it doesn't mean they wouldn't benefit from the broader license, since the authors granted those rights when they distributed the Software originally.
