Confusing subnet_cidr value

subnet_cidr = openstack_networking_secgroup_rule_v2.allow_higher_ports.remote_ip_prefix

I think this should either be openstack_networking_subnet_v2.subnet_1.cidr or removed. Referencing on a security group value, even if this value is that same as the network cidr, is confusing :)
