What is the logic behind using multiple nfps?

Hi,

I would like to ask what is the logic for using multiple npf according to this image? How you determine the valid positions? More specific how to know that polygon will be placed outside the multiple nfps?

In the image below it seems good when there are two the same haxagons. But incase of other forms when there is boolean union of nfps and the figure is inside of polygon how do you avoid collision?

When two or more parts have already been placed, we can take the union of the NFPs of the previously placed parts.
