The varnish image purge module does not take into account the active purgers. Instead it only purges the URL on it's own instance.
A list of purgers is being declared within varnish_image_purge_entity_update, but is then never used again.
Add multiple varnish instances and then try to purge a media item, for example.
Actually ensure that the URIBAN is being issued on all purger instances.
