The body diode of the 'backwards' (top) MOSFET blocks reverse current flow.

You still haven't explained the point of the 'forward' MOSFET.

The "protection" is just keeping the driver from providing too much voltage to the mosfets. No more
Generally the zener is used to prevent transient conditions from exceeding the "Absolute Maximum" spec for Vgs:

VGS Gate-to-Source Voltage ± 20 V

Is the gate to source voltage of the 'backwards' MOSFET adequately clamped?
