Misunderstanding of variable'a names

I'm a little confused. We have error variable in dataTaskWithRequest closure expression, also we create constant error in another closure. Do I understand correctly that these errors are not the same? And error constant that we've created we passed in completion, but what do we do with error from daraTaskWithrequest?
