May be useful if sentence on caching were added to this part?
"If you can still see protected entries under those circumstances once you have logged out, you will be seeing a stored version of the page in your browser. To see an updated page you will need to Refresh your browser and/or clear its cache".
(and then link to a relevant FAQ in further reading if felt necessary)
That's two sentences. I'm sure it can be written so it's shorter too.
Rationale: support requests where people enquire about seeing protected entries elsewhere (due to reason covered in FAQ) could re-green in theory if they log out and then view a cached page (unless they understand the cache issue already).
