Example: server1 with the following interfaces:
172.19.0.1, 172.20.0.1, 172.21.0.1

define host server1 with IP address 172.19.0.1

define service ping1 on host server1 with IP address 172.19.0.1
define service ping2 on host server1 with IP address 172.20.0.1
define service ping3 on host server1 with IP address 172.21.0.1

define service disk1 on host server1 depends on ping1,ping2,ping3
...

If one of the ping tests fails the depending tests won't be executed.

What is the advantage of your method? You define a logical grouping of the 
interfaces. Which interface do you define as the parent server? Where do you 
put your services (to the parent server host or to the interfaces)? What is 
the result if one of the "interface" hosts will fail?
