WEBENCH® Tools: Why Webench power tool suggested using this Hot-Swap Controller (TPS2420) for my design?

Tool/software: WEBENCH® Design Tools

Hi,

I was trying to build dc to dc converter that has one input which is anywhere between 9V-20V and has 4 outputs: 5v @ 2.5A, 3.3V @ 2.5A, 3.3 @ 1.5A, and 1.5V @ 1.5A. So, I sequenced the outputs and checked the Hot-Swap box and clicked next, then I noticed that my generated circuit has the TPS2420 as a Hot-Swap Controller which can have 4A as a maximum output current while the total of needed currents through the 4 outputs should be around 8A !!!!

Kindly, what is the thing that I'm misunderstanding here?
