pressureInletOutletVelocity boundary conditions

Can someone explain what the "pressureInletOutletVelocity" boundary condition really does? The simualtion is driven by a pressure. The outlet is prescribed a zero pressure and the inlet is prescribed a sine wave which goes both positive and negative.
The manual says:
The inletOulet switches U and p between fixedValue and zeroGradient depending on direction of U
The pressureInletVelocity determines the velocity based on flux when p is known.
The confusion is during the negative portion of the sinewave what does the inletOutlet do?
Thanks in advance
