No, it's the other way around. mod_expires uses the insert_filter hook to insert its filter before your handler is run (and how could it be otherwise? Output filters are there to post-process the content your handler generates). Have a look at ap_invoke_handler() in config.c, that should give you a handle on how the filter chain works. But don't hesitate to post your questions if you have them, of course. :)
