But we are talking about stress deforming the bottom layer of lead shot but not the top layer. So, in case 2, the bottom acrobat's feet have three times more stress than the top acrobat's feet and so his feet are more likely to be deformed than the those of the acrobat on top. I repeat, the bottom acrobats feet are supporting the weight of three acrobats, the top acrobat's feet support just one. But the mass of the three acrobats is the same in both case one and case two.

In my analogy the three acrobats are identical.
