pageFlowScope doesn't empty itself, but:- it is window-specific
- there's a limited number of pageFlowScope tokens saved

So, in that sense, it does clean up.  The point of the sentence
you quote is that as you move from page to page, pageFlowScope
keeps accumulating objects, unless you manually remove them.
