There is a kind of "rolling upgrade" promoted in the documentation which is really "rolling one-off patches." Applying *qualtifying* patches using opatch to RAC nodes one node at a time is one valid argument to having separate ORACLE_HOMEs. There are also several other arguments in support of such a practice, such as decreased impact from someone messing up ORACLE_HOME and added redundancy if they are placed on different arrays.

For a while they were saying that a Shared Oracle Home for RAC was a bad idea because "you can't do a rolling upgrade" with a single shared Oracle Home. Then people started calling them on the fact that you can't do a rolling upgrade AT ALL without Data Guard involvement...
