Yes, when I made a more official writeup of this I included the listed MOS doc along with checking for INSTANCE_... Of course our situation includes jdbc and those connections don't even get "INSTANCE_..." included in the final redirected connection. This is also listed in the same MOS document, although near the bottom in a small blurb. The only thing left at this point is checking "lsnrctl service" on a node and note any listed services with connection counts to other instances. Those are ones redirected, of course those counts are cumulative since the listener was last restarted.

Dave,
If the connection is redirected from another node, the listener log will have INSTANCE_NAME=... in the line (see Note:263599.1). You can grep -v those lines and see if the database logons tally up to the listener entries.
