The redirector knows about it by the simple fact that stdin is EOF.

Squid keeps the redirector in the table until the redirector acknowledges
the close (by closing it's stdout) and exits, but it won't (and can't)
send any new requests there as the communication channel squid->helper has
been closed.
It can happen perfectly fine that a helper is shut down while processing a
request. In this case the helper should send the response when done
processing the current request and then exit.
