That's right. When these routers are "interested" yet "decline", the
mail will get bounced as "Unroutable address" (which is what you want.)
If they are "interested" and "accept", (the lookup with possible
subsitution suceeds) then processing continues in the routers listed
below the current router - such as delivering to a local mailbox. The
"domains" line is a precondition on the router stating which domains it
will handle. If the condition is not met, it just ignores the router.
