SmoothDamp on Camera Movement moving faster in X.

I know I am missing something seriously silly here but I cannot figure it out. Could a kind soul put me out of my misery, please?
The following code works great as long as the call to BindCamera() is not made. If I try to limit the camera movement to the world edges, suddenly the camera moves faster in X than in Y when scrolling back to the target. Why in the world would that happen?

Code (csharp):

1.  
2.     // Update is called once per frame
3.     void Update ()
4.     {
5.        UpdateCameraPosition();
6.        BindCamera();
7.        SetCameraPosition();
8.     }
9.            
10.     private void UpdateCameraPosition()
11.     {
12.         //If I am scrolling just move the camera according to the mouse input
13.         if( m_scrolling )
14.         {
15.            Vector3 inputSlideAmount = m_prevMousePosition - Input.mousePosition;
16.            m_scrollAmount = new Vector3(
17.                     inputSlideAmount.x * m_scrollRatio.x * parallaxRation,
18.                     inputSlideAmount.y * m_scrollRatio.y * parallaxRation, 0 );      
19.    
20.            m_cameraPosition = m_cameraPreScroll + m_scrollAmount;
21.            m_cameraVelocity = Vector3.zero;
22.         }
23.         else
24.         {
25.            //If I am not scrolling and there is a target for my camera
26.            //then scroll the camera back to center on the target
27.             if( m_target !=  null )
28.             {
29.                 m_cameraPosition = Vector3.SmoothDamp(
30.                          m_cameraPosition,  
31.                          m_target.transform.position,
32.                          ref m_cameraVelocity,
33.                          m_dampingFactor );
34.             }
35.         }
36.     }
37.            
38.     private void SetCameraPosition()
39.     {
40.         transform.localPosition =
41.                     new Vector3( m_cameraPosition.x,
42.                                  m_cameraPosition.y,
43.                                  transform.position.z);
44.     }
45.            
46.     //Do not allow the camera to go outside the world boundaries
47.     private void BindCamera()
48.     {
49.         m_cameraPosition =
50.         new Vector3(
51.              Mathf.Clamp(m_cameraPosition.x, m_minCameraPosition.x,  m_maxCameraPosition.x ),
52.              Mathf.Clamp(m_cameraPosition.y, m_minCameraPosition.y, m_maxCameraPosition.y ),
53.                  m_cameraPosition.z);
54.     }
55.
