i can't help much with your first question.  i'm quite certain that it's not an 
update-state! vs. set-state! thing.  it seems like updating local component 
state in IWillUpdate does work, so i don't know whether that doc needs updating 
or if that's behavior that is unsupported / anti-pattern.

but as to your follow up, this section of the docs for IWillUpdate is 
definitely accurate:

"Not called on the first render, will be called on all subsequent renders"

you can see here IWillUpdate is not called on the first render, but is called 
on subsequent renders (when you click the button):
