My customer try to short 5V to GND, they found the POK pop up after POK drop. Is this OCP behavior?

Far, normally short 5Vout will trigger UVP, IC will latch- off, what’s connection of the signals in waveform in the schematic? please upload your schematic for review, and describe the details of how customer do the short test? with short line connecting Vout to GND or ….?
