Yes, that would probably be the case. Bear in mind that you do NOT need to run multiple relay agents for this, it gains you nothing in terms of functionality, but creates more work and problems like the one you've found.
So I'll repeat the question : what is it that you are trying to achieve that makes you think you need this setup ?
