Clear up inconsistency in authorize_resource examples

[kyletolle]

Forward

While reading through the source code and its examples, I noticed what I believe is an inconsistency in the example code and example explanation for authorize_resource.

I created two comments on the related lines in the commit where this was introduced. The comments are asking whether my hunch is correct.

25a1c55#L2R118

This pull request is created in case my hunch proves correct, and the documentation needs to be updated to reflect that.

Change Description

Changed the explanation of the code in the example to have the same references and order as the related example code.

Previously, the example code referenced a book, whereas the explanation of that example code mentioned a show. The example and the explanation did not match.
