TPS2640: TPS26400: reverse polarity protection

Part Number: TPS2640


I am using TPS26400RHFR as a reverse polarity protection. I noticed that the reverse voltage would pass through to the output. When the input -24V, the output voltage -0.4V.

Input and output voltages are shown below.

The schematic is shown below

Is this the correct result ? I thougt that output voltage should be 0V.
