RMAN crosscheck command and ITSM for DB 5.2

*SMers

In the ITSM for Databases v5.2 (Oracle) manual SC32-9064-00 it states:

"Be aware that the RMAN crosscheck command will expire backups on the Tivoli
Storage Manager Server that belong to a different Tivoli Storage Manager
node or file space."

...three times (relating to policy set up, deleting old backups and using
utilities).

Our DBAs were understandably a bit concerned having seen this and would like
some clarification, since they use crosscheck as part of their backup
expiration/deletion scripts.

It seems to indicate that the crosscheck command will expire Oracle backups
for ALL our nodes backing up to a given TSM server, although i'm sure this
can't be the case.
I presume that this is true only if you don't specify the TDPO.opt file
during deletion script?

Can anybody confirm or refute this as it's not very clear and it's a alarmed
our DBAs somewhat
