...The sound of that to me is OK! Double pole switch for flouresant lighting, cool!

I don't think that is what they mean. I believe they want a disconnect on the line side of each ballast within the fixture. The cheapest and easiest way to accomplish this is with a 2 pole connector (like a Molex) that would be supplied by the ballast manufacturer as part of the line leads. If you need to change the ballast simply pull the connector apart. No shutting down lighting or working hot.
