Variables that start out populated, such as @INC, will exist in order to be populated. Variables that start out unpopulated, such as @ISA or $AUTOLOAD, won't.

That doesn't make it intuitive, although I do believe it's mostly consistant.

Update: Added the italicised word above as per ryantate's comment below.
