It could just be my two cents worth, but I was under the impression that
split-horizon only affected distance-vector routing protocols and that
link-state protocols with their more sophisticated LSA's gives the router a
better view of the entire internetwork, and so split-horizon isn't necessary
and doesn't apply.
I know that EIGRP is a hybrid routing protocol... but it is typically
considered a link-state one.
Just stating what I think the explanation could be.
