It is more easier to understand, e.g., how to rotate an object which is not located at origin if the sequence tran(-p), rot(a), tran(p) is used than if the final matrix is used. That is why I think the system is more "correct". No need to ask which is performed first: rotation or translation. Keeping tran and rot nodes in the graph makes the system more complex but the nodes can be optimized away if the cylinder node supports translation and rotation.
