Does SCCM 2012 monitor SCCM 2007 as well?

Question

I have a SCOM environment and I have two SCCM environments - one is 2007 and the other is 2012R2. We are migrating from 2007 to 2012R2. I have both SCCM 2007 and 2012 MPs imported.
One thing I've noticed is that all the objects from the 2007 MPs are labeled ConfigMgr 2007, while the objects from the 2012 MPs are just labeled ConfigMgr. And when I create a subscription to send all alerts on ConfigMgr (I filtered to only show objects
in Microsoft.SystemCenter2012.ConfigurationManager.Library MP) it will send out notifications for all SCCM alerts. 
So does the 2012 MP monitor 2007 as well? And if so, how can I create a subscription to only notify for 2012? I currently set up the subscription directly against the 2012 servers, but I'd like to have it go against the application instead.
Thanks.

Answer 1

Yes, we have Exchange. But it doesn't make sense that a subscription criteria set to the ConfigMgr application would send alerts regrading Exchange. Maybe because the SCCM client is installed on those servers...?
False alerts as in SCOM thinks one thing but its not actually the case. For example, thinking that an Exchange server is a SCCM server. And Alerting on SCCM 2007 instead of 2012.
