I think he's referring to (from RFC1122, 3.3.1.2,
http://www.cis.ohio-state.edu/cgi-bin/rfc/rfc1122.html#page-48):
under DISCUSSION,

	When there is no route cache entry for the destination host
	address (and the destination is not on the connected
	network), the IP layer MUST pick a gateway from its list of
	"default" gateways.  The IP layer MUST support multiple
	default gateways.

3.5 is INTERNET LAYER REQUIREMENTS SUMMARY.

He may wish to clarify.
