DRV8711 What happens with Incorrect Stepper Motor Hookup?

Hello TI Motor gurus,

I'm debugging the DRV8711 in my prototype, and came across a "System wiring bug" that has existed in previous Motor designs. 

What happens if you incorrectly wire a Stepper Motor to the HBridge (driven by the DRV8711) in the following Configuration?

DRV8711_HBridge               StepperMotorCoil
A+                                        A+

A-                                         A-

B+                                        B-

B-                                         B+

I have done this empirically and it still seems to turn the motor, but I imagine this is applying incorrect torque to the motor since it is driving the Current at the incorrect times (180-degrees phase-shift on coil-B).
