There's actually a range of behaviors to consider here:

1. $Vend::RedoAction can be set to true by your actionmap sub, in which case the actionmap portion will be parsed again based on the catalog-relative path in $Vend::FinalPath

2. If you want your actionmap to then be followed by standard page processing, yes, it needs to return a Perly true value

3. If you want your actionmap to generate the response itself directly, and *not* do standard page processing, your actionmap should return Perly false so that do_page will not be called.
