2.47rc2 Snap Enhancemnt - Align Rotation ??

Yesterday, I tried out 2.47rc2 and noticed the new snap features.
The added ability to snap to lines and planes is a very nice addition.

The problem is that I cannot understand the other new snap feature: “Align Rotation with the Snapping Target”. I tried it out in all the combinations I could think of but the new feature seemed to make no difference at all in the final result. The only difference I could see was that a white “normal” line was attached to the cursor as I moved the mouse around to the snap target.

Does anyone know what “Align Rotation with the Snapping Target” is supposed to do or how it should be used?
