And by TRUE he means FALSE. Or possibly !isset() or !empty(). You get 
the point. To be clear the following two statements are both TRUE:

If something is not set or NULL, then isset() is FALSE. if something is 
not set or NULL or empty array, 0 or '' or '0'  then empty() is FALSE.
If something is not set or NULL, then !isset() is TRUE. if something is 
not set or NULL or empty array, 0 or '' or '0'  then !empty() is TRUE.

That is all.
