I fail to see a difference.

So do I.  However, it is prudent to use a definition from the ECMAScript 
Language Specification when discussing implementations of ECMAScript.

Yes.

"in scope" is a necessary, but not a sufficient criterion.

You can never be sure that your code is only executed in the global context, 
and the global context always can enforce strict mode.  In fact, it is 
reasonable to assume that it is not, because of the side effects and of the 
prevalence of the module pattern.

It is not logical to use approaches that make code less compatible than it 
needs to be.
