Crazy. Didn't see this as it worked for me in multiple tests. The issue is the scheduler has to publish the content or it's hidden. Hidden content is a 404, but it ends up on the Tony Davis article. We're working on a couple fixes, but they're not deployed. The scheduler, no idea. Tagged that as a highest priority item.
Long story:Wordpress accounts for possible truncation of URLs, or slight changes. If it gets a missing URL, before kicking a 404, it does a "like" search for articles that might match. Then it returns one of those. That seems insane to me, but we discovered this in tracking down a few items across the last week.
In our case, because we have a lot of URL redirects, and some are not yet programmed in, we have some content that kicks out 0 rows, which causes WordPress to do a like search of sorts. I don't want to spend time tracking the technical details of what happens, but I've asked that we note the 404 and drop the user to the search page.
