Security Confusion

So I have a node (category) I don't want my users to see, and it has nodes (forums) below it I do want them to have access to assuming they have a direct link. I thought I had a pretty good understanding of the permissions system ( based off that article and several others, but it doesn't seem to be working how I'd expect.

  • Restricted Node - View: Revoke
    • Child Node - View: Allow
It was my understanding that this Allow would override the Revoke above it.

I also tried similar configuration with the Private Node settings...

Is what I'm trying to accomplish possible?
