I guess that the other nodes still gossips about the removed node. The
node isn't removed from gossiper in the cluster until some amount of
time have elapsed. My guess is that you haven't changed the cluster_name
property in the cassandra.yaml on the removed node.

I have an existing Cassandra Cluster. I removed a node from the
cluster. Then I decommissioned the removed node, stopped it, updated
its config so that it only has itself as the seed and in the
cassandra-topology.properties file, even deleted the data, commitlog,
and saved_caches. But as soon as I start it backup it is able to join
back to the cluster. How does this node know the information of the
existing cluster and was able to join it ?
