Octopus merge: unique (?) to git, but is it useful?

I think that octopus merge (merge with more than two parents/legs) is 
feature which is unique to git (isn't it?).  Do you remember perhaps 
why it was introduced?  What does it give, beside making it difficult 
to convert git repositories using this feature to others SCMs, for 
example for comparison:
