The image shows two native roles on the left side (one above the other). The native role from spoke 1 connects eventually to a Transformation Binding Role. The native role of spoke 2 also connects to a Transformation Binding Role. Both roles then connect to the same Business Role. The text at the bottom of the image says: If correlation exists between any native events across native roles of different spokes, the above role design is invalid. If no correlation exists between any native events across native roles of different spokes, the above role design is valid.
