That line is only relevant for when you're starting your cluster and you need to define your initial tokens in a non-random way. Random token distribution doesn't work very well when you only use 4 tokens.
Once you get the cluster set up you don't need to specify tokens anymore, you can just use allocate_tokens_for_keyspace.
