Dont understand your question ?
If you have 2 masters replicating to each other, yes you can a have a single slave hanging from either those servers.
Things to keep In mind
Each server have unique server id
Make the slave read only
If you have very little experience in DBA'ng and particular with mysql the I suggest you look at other products.
But it is fairly easy to set up and administer, we have quite a few instalations of this nature, multi master with lots of slaves hanging of the masters !
