This is correct.  "public" does not mean "available to all users", it means
"available to all instances".  At this time only single-instance Oracle is
available for V6.  Multi-instance is only relevant to sites which run Vax
clusters and want to access the same database with a set of server/background 
processes running on several cluster nodes.
