From Gentoo Wiki
It appears that as of sys-apps/openrc-0.13.11 'need' and 'after' dependencies have subtly different semantics. Only 'need' dependencies cause the dependant to wait for the dependee to reach the "started" state, while 'after' and 'use' dependencies merely ensure services are started in the correct order.
