Understanding UnityEngine.Input.touches

Given the following inside "void Update()":

 Debug.Log("////START TOUCHLOG////");
 foreach (var touch in UnityEngine.Input.touches)
 {
     Debug.Log("T" + touch.fingerId + ": " + touch.phase + ", " + touch.position);
 }
 Debug.Log("////END TOUCHLOG////");

Using 3 of my fingers not touching close, to:

1. Touch first finger

2. Touch second finger elsewhere

3. Touch third finger elsewhere

4. Repeatably tap first and second finger on the same spot.

Can someone explain why these loggings occur:

A) Same touch ID appears twice?

 ////START TOUCHLOG////
 T1: Ended, (624.0, 256.0)
 T1: Began, (624.0, 256.0)
 ////END TOUCHLOG////
 ////START TOUCHLOG////
 T2: Moved, (530.0, 776.0)
 ////END TOUCHLOG////

B) No "end" event for T1. T2 becomes T1 next frame.

 ////START TOUCHLOG////
 T0: Moved, (425.0, 766.0)
 T1: Began, (508.0, 323.0)
 T2: Ended, (912.0, 256.0)
 ////END TOUCHLOG////
 ////START TOUCHLOG////
 T0: Moved, (425.0, 766.0)
 T1: Began, (912.0, 256.0)
 ////END TOUCHLOG////

This issue occurs when building to WebGL and running on Windows 8 in chrome using the touch screen.
