That's correct. If you run describe cluster normally you'll see something
like:

Cluster Information:
   Snitch: org.apache.cassandra.locator.SimpleSnitch
   Partitioner: org.apache.cassandra.dht.RandomPartitioner
   Schema versions:
        3a0f6a80-7140-11e1-0000-511aec3785ff: [IP_OF_NODE,  IP_OF_NODE ,
IP_OF_NODE ]

If there are troubles with the schema multiple will be shown of them, like:

Cluster Information:
   Snitch: org.apache.cassandra.locator.SimpleSnitch
   Partitioner: org.apache.cassandra.dht.RandomPartitioner
   Schema versions:
        3a0f6a80-7140-11e1-0000-511aec3785ff: [IP_OF_NODE,  IP_OF_NODE ]
        4e252abe-7140-11e1-0000-511aec3785ff: [IP_OF_NODE ]
