Illustrator :: Cusp Point Changes To Smooth Point

I was doing the following steps when I encountered this problem:
 
1) I created a V shape with the Pen Tool.

2) After having changed my default selection tool to the Direct Selection Tool (so that I can use it later), I used the Convert Anchor Point Tool (Shift-C) to drag at the V junction to change it to more of a U shape & thus also creating a Smooth Point there, like this:
 
3) Then I grabbed one of the direction handles & dragged it a bit to make it a Cusp point. Like this:

As soon as I did this, the other direction handle disappeared & the anchor point also became deselected.

4) So I temporarily switched to the selection tool (the Direct Selection Tool in my case) by holding down the Cmd key and clicked on the anchor point.
 
Result: As soon as I clicked on the anchor point to select it and also make the other direction handle visible, the anchor point became a smooth one & the shape of the path changed dramatically - i.e., the cusp point I created was gone (see fig.)

and I had to rework on the changed path.
 
Is this expected? BTW, I'm working in Illustrator CS6 (Mac).
