PMFR It doesn't need to be 🙂 Did you grasp the above example? Im here for your questions. The texture node isn't required in all your masks.Maybe the name is misleading. The workflow is ,you make your heightfield you pin that as underlay and you produce masks(slope,texture,flow,the wear,deposit output of your erosion etc). Then you plug two satmaps in your first two masks and combine them. Then you combine the previous combine node with the next satmap etc.
