DRV777: COM Voltage Spec Clarification

Part Number: DRV777

I am needing to drive a 12V unipolar stepper motor. The datahseet states that the COM voltage is recommended at max 16V, but Figure 4 on Page 7 illustrates an example of driving a unipolar stepper motor suggested a voltage no higher than 8V on the COM. Could I get some clarification on the ambiguity.
