A define placed inside another define can only be used locally by code in the 
enclosing define.

What you are probably referring to is how a define that is global to code in 
one file can conflict with a define in another file if the names are the same. 
  This is due to all script files are read in to a single block of memory used 
by the interpreter.

To avoid the problem, nest defines when you don't need something to be 
accessible from in another define in a given file. If a define (ie. function) 
needs to be global so it can be access in multiple define blocks in a file, 
avoid using generic names that someone else might have used in another file. 
One way to avoid name collision is the prepending of your initials to your own 
defines.
