Rotation

The rotation (as a default and without the LRA extension module for SE) is incremental between bends. So, once a bend is performed the rotation is considered to be 0 at that point in time and the rotation amount is based upon the amount of rotation between bends.

In the above picture notice how bend #4 has a rotation of 0. This shows no rotation between bends 3 and 4.

NOTE: If you need to have absolute rotation like that need when the material held in place by a chuck then the LRA extension module is needed.
