RhinoCommon How to extend surface by negative value?

In Rhino I can do:

Select surface edge 

Extend by let say -1 unit.

In rhino C# I type :

    A = x.Extend(IsoStatus.East, 1, false);

works well and extends surface, but 

    A = x.Extend(IsoStatus.East, -1, false);

outputs null

How can I achieve desired result for negative extension?

So for negative values it is surface split.

Thank you The Lord.

May the force be with you.

You mean the dark option I do hope.

Notify if you want a C# that inquires a surface and does various (mostly useless) things.
