Ok, now that I am debugging the right code... Yes, the expunge function
registered for the Trash folder is vee_expunge in camel-vee-folder.c.
vee_expunge has one line:

((CamelFolderClass *)((CamelObject *)folder)->klass)->sync(folder, TRUE,

So, it calls the sync function. Correct me if I'm wrong, but it looks
like any folder which is to implement message expunging when the user
clicks "Empty Trash" needs to implement the _sync_ function in such as
way that deleted messages really can be expunged. Writing an mbox or
spool expunge function won't work as it won't get called via a vTrash
folder expunge.
