If you think of your filter list as an assembly line, each message
passes through each filter, if it triggers on that filter the action is
taken.  If there is no stop processing action in that filter the message
is passed along to the next filter for processing.  Most non-trivial
filter systems utilize a similar approach.  This permits very complex
actions to be created.  And sometimes you may want to have a filter that
takes some action when triggered but allow the message to proceed
through the rest of the filters.  

In this case it is better to stop processing the message to prevent
duplicates and such from showing up because subsequent rules were
triggered.  Of course you need to review your filters to make sure a top
level filter prevents your other filters from never being used.
