$n1 is simply a global. It is global to everything (including subroutines and nested blocks) from the point where it is declared onward.

Actually no language I can think of (of the small number I've used) hides global variables from subroutines/functions/class members. Is there a bigger picture here that is leading to your confusion?

Update: Fletch is quite right that I'm playing fast and loose with nomenclature here. C's 'file scope' is the notion I intended by "global". My appologies for any confusion caused.
