 What is this?

This is from a Mulia of mine that uses two split complex number iterations before it iterates using a traditional Mandelbrot set using good ol' complex numbers. Here is my per point iteration function:

iterate_complex_split_point(
     ct::plot::cairo::plot_2d& scene,
     glm::vec2 p0,
     unsigned long x,
     unsigned long y,
     unsigned long n
) {
     glm::vec2 z = p0;
     glm::vec2 c = z;
     //c = { -.75, 0 }; // Julia mode...
     float mindis = 9999999.f;
     z = ct_complex_split_mul(z, z) + c;
     z = ct_complex_split_mul(z, z) + c;
     for (unsigned long i = 0; i < n; ++i)
     {
         z = ct_complex_mul(z, z) + c;
         float zdis = glm::length(z);
         mindis = glm::min(mindis, zdis);
         if (zdis > 2.f)
         {
             return;
         }
     }
     scene.set_pixel(x, y, CT_RGBF(mindis * 10.f, 0, 0));
}
