I get by your explanation that the added benefits are the icing on the cake.

  If I understand correctly, the idea is that by initializing the 
variable, and then testing something specific against it, because we 
know it exists, contributes to a more robust and secure app. The 
reason why is that it might prevent someone from somehow mangling URL 
or POST data, and that because we have to test for something more 
than the existence, it adds to security. Is this correct?

Some are born great. Some achieve greatness.
Both are excellent contacts to keep in your Rolodex.
