Ah, missed that. Thanks for the pointer. 
While we are at it, the doc says that if I am doubling the strength of my cluster, and I assign calculated tokens to the new nodes, i don't need to do the nodetool move for old nodes. Won't I have to assign the old nodes with their new respective tokens too? If I had 4 nodes and I add 4 more, the token distribution for each node changes. Then how could I get away with not assigning old nodes with new tokens?

Have you done step 6 of the 'To add nodes to a Cassandra cluster' of
