Strange behaviour - arrays or treeview?

In hunting down a problem I created a simple form.

Public Class Form1

   Private mOne As TreeNode
   Private mTwo As TreeNode

   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

       LoadNodesA()
       'LoadNodesB()

   End Sub

   Private Sub LoadNodesA()

       mOne = TreeView1.Nodes.Add("One")
       mTwo = TreeView1.Nodes.Add("Two")
       TreeView1.SelectedNode = mTwo

   End Sub

   Private Sub LoadNodesB()

       Dim nodes(1) As TreeNode
       nodes(0) = New TreeNode("One")
       mOne = nodes(0)
       nodes(1) = New TreeNode("Two")
       mTwo = nodes(1)
       TreeView1.Nodes.AddRange(nodes)
       TreeView1.SelectedNode = mOne

   End Sub

End Class

The behaviour I wanted is given by LoadNodesA(). LoadLoadsB() gives a
different result. Can someone explain why the difference arises and why it is
meant to happen this way?

Thanks for any comments.
