If you refer to the following architecture:

Node1_DB1 <--> Node2_DB1

And you want to create a new database DB2 on Node1 and have it
replicating to DB2 on Node2 with BDR, then yes, you have to follow the
same process used to create the first BDR group.

Keep in mind you'll need more slots and replication connections, so
check the values of max_replication_slots, max_worker_processes and
max_wal_senders.
