Exactly. I'm guessing most didn't fully read the article. What I got out of it was that the NSA was really concerned about being sure they were correct that Snowden didn't in fact officially raise any concerns and that all they could find that was even close to this was a single email about a trick question on a test. One could argue the NSA could be trying to make sure there was no proof rather and that's fine. This article though only finds evidence of a single email. I'd love to see more but this isn't it.
