[css3-2d-transforms][css3-3d-transforms] Relationship of CSSMatrix interface definitions

Both CSS3 2D Transforms [1] and CSS3 3D Transforms [2] define a CSSMatrix DOM interface.
One describes a 3x2 matrix, the other a 4x4 matrix. 

What is the relationship of these two identically named interface ? Is it intended for
the DOM to have separate object types for 2D and 3D matrices ?
