Because when the external ones are queries on foo.internal they return
an authoritative "no such domain".
If you need to make smart choices on which nameserver to ask depending
on the domain, you need to run a local nameserver with zone referrals,
e.g.
options {
forwarders { ext1; ext2; };
};
zone "internal" IN {
type forward;
forwarders { int1; };
}
then use
nameserver 127.0.0.1
nameserver int1
nameserver ext1
