12.1.0.2 RAC and redo log threads

Hi all

According to the notes I've read, a RAC instance has a unique thread number and a redo log thread will belong to that particular instance.

I have queried by 2-node RAC database and found that the redo log threads actually can belong to both instances.

Has this changed in 12.1.0.2 or did I misunderstand the RAC redo log threading concept?
