I like to think Set's form is emergent and takes whatever form you want see, or a group of people want to see. Set sort of emerges from the chaos, and that's what his image does for me, sometimes I see a dog, sometimes an anteater and so on. I think the Egyptians probably imagine that the world is always emerging from the primal chaos, it's not something that simply occurred in the past, and it's up to us what we make of it.
