Usability: Confusing Configuration text

The secure pages configuration page provides 2 radios for, "Pages which will be be secure: Make secure every page except the listed pages OR Make secure only the listed pages."

Then there are two textareas: Pages and Ignore Pages.

Does this mean that the "Make secure every page except the listed pages" setting ignores the "Pages" textarea configuration? And does "Make secure only the listed pages" ignore the "Ignore pages?"

Perhaps the "pages" textarea could be disabled via javascript when "Make every page" is selected.
