Did you try, or it's just your guess? There's no "variable scope" concept in 
nginx configuration. And it mostly has declarative nature, therefore, the order 
of most directives is not important, unless it is specifically documented.

btw, your example config also wrong. If look at the documentation, you will see:

server
  syntax: 	server { ... }
  default: 	—
  context: 	http
