My DS4 will be having some testing in the spring when he is almost 5yo (we want to get it in before school). the psychologist that we are going with is well known in working with gifted children and she says that she gives this test as well. I think it is a basic test to see their level of creativity, and whether they have difficulty being creative, seeing outside the box, etc. Maybe how literal they can be as well. That's my (limited) understanding of it.
