A multiple-instance setup is NOT the same thing as Oracle Parellel Server. Consider replication with MASTER and SNAPSHOT sites. This configuration is definitely a multiple-instance setup and differs greatly from a Parallel server configuration. To wit:

PARALLEL SERVER: Multiple instances, single data source, i.e., only one set of database files for the two or more instances accessing the data.

REPLICATION: Multiple instances, multiple data sources, all synchronised.

I can understand how this can be confused, but a bit deeper read into the documentation would have cleared this up.
