Maybe we are talking of two difference situations -
1. If only the ports are stealthed, the router could respond in other ways to
say it is still active (ICMP) but ports are not. Also, this would allow the
router to report that the system is not present if turned off. By technical
RFC interpretation, a router should never drops pings so this would happen.
2. If the router is completely stealth - drops all communication and doesn't
respond to pings (discard WAN pings enabled) - how does it respond back that
anything (ports or otherwise) does/doesn't exist? I've been referring to this
second scenario here but I wasn't clear enough. What way does this completely
stealthed router communicate back, that's what I don't understand yet.

It's not the same thing. If the system is turned of the router will
report that the *system* is not found. With a stealthed port, the
router reports that the *port* doesn't exist. It can't determine
whether or not a port exists unless the system is connected.
