I'm attaching a few photos (hopefully!) that clearly show their differences, the one with the trailing orange wire is the magneto with the anti-clockwise drive.
Looking at the pictures of the points I would say the cam could satisfactorily rotate either way in both.
The rotation timing issue would be the build up of the spark.
