Mssql2012 - traversing hierarchy not working as expected. please advise.

Question

Techies--
When I try to look for descendent organizations, I am seeing the level I am descending from and the descendents (screen shot).  I did not expect to see the row hightlighted.
When I try to find the ancestor on level 1 for OrgId 3, I don't receive any rows. I expected to see only the highlighted row. I have either generated the data incorrectly, or I am thinking about hierarchies in a wrong way.
Here is the sql for the queries
-- query#1 (descendents)
declare @OrgIdofInterest hierarchyid
select @OrgIdofInterest = OrgNode
from [stakeholder].OrganizationInheritance
where OrgId =2;
SELECT
orgtree.OrgNode.ToString() AS Text_OrgNode,
orgtree.OrgNode,
orgtree.OrgLevel,
orgtree.OrgId
FROM stakeholder.OrganizationInheritance orgtree
where OrgNode.IsDescendantOf(@OrgIdofInterest) = 1
-- query #2 (ancestor[s])
declare @NewOrgIdofInterest hierarchyid
select @NewOrgIdofInterest = OrgNode
from [stakeholder].OrganizationInheritance
where OrgId = 3;
SELECT
orgtree.OrgNode.ToString() AS Text_OrgNode,
orgtree.OrgNode,
orgtree.OrgLevel,
orgtree.OrgId
FROM stakeholder.OrganizationInheritance orgtree
where OrgNode.GetAncestor(1) = @NewOrgIdofInterest
Here is the build SQL for the tables and stored proc.

Answer 1

IsDescendantOf
Returns true for all the nodes in the sub-tree rooted at parent, and false for all other nodes.
Parent is considered its own descendant.
GetAncestor
Returns a hierarchyid representing the
nth ancestor of this.
ordid=3 is the ancestor of nobody.
