No, he's saying if you work in a department that has been given the power to oversee security at your organization, then your job is as much to service your customers (the other departments) as much as it is to ensure their safety. Trying to use that position as a means to be change-averse or to power-play is just going to ultimately lead to people finding another way.

There's also a real line between ultimately flaunting the rules and "just trying to get your job done" in these kinds situations. Obviously if you're imperiling classified secrets that distinction will not apply to you. But for most other people this is just an item in the toolbox for effecting the change you want to see, lol.
