ok I see that now. Maybe this is a lesson in anonymous closures I missed, but I know that the window object is essentially the default global scope, though the assignment is inside an anonymous closure so I expected the 'this' object to not be the global scope, which as you point out, it is. It makes sense now, thanks.
