They are being very specific so that there is never any ambiguity over which variable
they are talking about if there are more than one with the same name in different
scopes (ie variables.production and URL.production). Variables comes first in the
search order so it isn't THAT necessary... EXCEPT for query variables - they come
before "variables". It is said to be faster when you are explicit but since
"variables" is the second scope searched it's probably not much faster.
