There is another thread "MirrorMode and chaining - are slaves

which has caused me some confusion about MirrorMode and N-Way Multi-Master Replication.
Is the difference between MirrorMode and N-Way Multi-Master the
number
of nodes? 2 nodes = Mirror Mode, 3+ nodes = Multi-Master? But both
use
the exact same configuration?
If this is the case the documentation does not make this clear at
all
and using the MirrorMode directive in N-Way Multi-Master is very confusing. Why not "MirrorMode On" OR "MultiMaster On" ??
Is there a way to use two nodes in N-Way Multi-Master replication?
The key element of MirrorMode is that there is an external frontend that ensures that all writes are directed to a single server. Otherwise, there is no difference.
Should I change the docs for MM? We do writes to a single server to guarantee writes correct? If they are both the same, should we rename MirrorMode to a different key word?
We don't use the server URI in the MM example, maybe that section should be totally re-written as it seems to be confusing users.
Thoughts?
