Using BSNES+, we can see that it's a basic setup of 3 layers; two 4bpp foregrounds and one 2bpp background. Nothing out of the ordinary here, many games do this.
Asterix & Obelix however, combines not only parallax scrolling (moving horizontal slices of layers mid-frame) with this, but also priority switching mid-frame so that parts of layer 3 are in the background at the frame's top segment but also in the foreground at the frame's bottom segment. Neat trick, very similar to that which Yoshi's Island does sometimes.
