It clearly says: "...you get an hour of my time to discuss..." This is just the human-to-human interaction portion of the plan. The test cases and reports are likely running all month. I have a similar retainer program where each client gets a day of my time per month for a pre-paid fee, in which I address specific concerns they have. That doesn't mean I only work one day per month on their systems as there are scheduled cron scripts and monitoring that run continuously. His explanation could be worded better.
