This is not the case (i.e. you are reading this wrong  ). The 
FETCH_GENERATION_DELAY_MS constant specifies how much time
needs to pass 
before Pages already selected to be included in a fetchlist
will be 
re-considered for selection again, UNLESS they have been
updated with 
updatedb (after fetching).

This is to prevent selecting the same pages, if you run
FetchListTool 
twice in a rapid succession - but at the same time, if you
lost or 
discarded that fetchlist, not to wait indefinitely. 7 days
was 
considered to be a good optimum (some large fetch jobs may
run for days, 
so it could be a couple days before you have a chance to run
updatedb 
with the results of fetching).
