Did Sean Gorman's maps show the cascading vulnerability in Ohio?

So, the US Government wants to classify Sean Gorman's student project.
The question is did Mr. Gorman's maps divulge the vulnerability in the
East Coast power grid that resulted in the blackouts this week?

Would it be better to know about these vulnerabilities, and do something
about them; or is it better to keep them secret until they fail in a
catastrophic way?
