Right. Both of the ngx_http_finalize_request and
ngx_http_output_filter are asynchronous calls. So data might be later
flushed out upon new write events via the ngx_http_writer handler.

One good approximation for this is to register your own *pool cleanup*
handler in r->pool. The request pool will not be destroyed when
there's still pending data (don't get confused it with the request
cleanup thing created by ngx_http_cleanup_add, which gets called too
early for this).
