Content strategist - front and back end

In a recent article on the Content Marketing Institute site it posits that you need two types of content strategists - one for the front-end and one for the back-end. I contend that one person should be able to do it all, and if you don't have one person then you have a high risk of missing content or their components and getting bogged down with processes and approvals. The more people you have managing the content the more rigourous your governance and processes need to be.
Here is my take on what a Master Content Strategist does, in comparison with the article's division of front-end/back-end person:
