The bleed valve is opened while filling to know when the tank is filled to 80%. Been that way for ever.
Some untrained people were closing the bleed valve while still filling the tank. Get a little extra that way. That would result in an overfilled condition.
Soccer Mom would put the tank in the SUV and then go shopping for shoes. The gas would heat up and vent. The SUV would go boom, when she hit the power door lock button.
The OPD, Overfill Protection Device, was added for safety reasons.
Now Johnny can't blow up Soccer Mom.
The OPD can fail, as I discovered, while getting a tank filled by a drunk attendant. I should have known better then going there in the late afternoon. He got 5 gallons in before he stopped the pump. My DW asked me why Joe was sitting on the ground. I said " He's to drunk to stand "
I blead some off and exchanged the tank, when empty.
