Simplify self intersecting polyline

When I run simplify on a selfintersecting polyline I get the same geometry back.
After reading the documetation I expected to get a polyline divided into paths so that it doesn't selfintersect.

Is this a bug or am I misunderstanding something here?

Please review the following help documents.
http://resources.arcgis.com/en/help/soap/10.1/index.html#//01vp0000002v000000

As per this doc, self-intersections are preserved for polylines.

Thanks for your answer.

It was the second documentation I was previously looking at. It's also this document that I found referred in the API-doc.

I think the documentation is a bit ambigious.
"all overlapping segments are reduced to a single segment, and segments are split at intersection points. Output paths are created for connected sequences of segments"
Then the following illustration I think shows that the selfintersecting path (3) will be diveded into three segments (6, 7, 8).

Maybee the documentation needs to be updated?
