Other Parts Discussed in Thread: TPS2020, TPS2065


I hope I'm right here. I have question concerning the TPS2020:

Datasheet says that output voltage must not be higher than input voltage by more than 0.3V:

Figure 40 of datasheet shows a typical hot-plug situation. Assume that a high capacitance of let's say 100...220µF is connected from output to ground and that the load current at the output can be very low, so low, that this capacitance is discharged very slowly.

The same scheme can be found in figure 1 of this link as well by the way:
When the input voltage now suddenly drops, the switch is still on until the undervoltage lockout of TPS2020 turns it off at about 2...2.5V input voltage. If the input voltage furtherly drops, the output voltage can be higher than the input voltage, right?
Will the TPS2020 withstand this situation? Or is a diode needed connected from output to input? If so, is a Schottky sufficient? Why does the TPS2020 not have a diode already built in? Or has it one? If so, which current can it withstand?
Please have a look at the datasheet of TPS2065 too. It has a different output voltage range specification (-0.3V to 6V) in the absolute maximum ratings:

So I ask myself: Could there be a typo in the datasheet of TPS2020?

Thanks in advance,
