What is an overlay?

Specifically in relation to this new product
https://www.daz3d.com/krdx-dirt-fx
I have many KindredArts decal-based products, including existing ones with dirt etc. This one mentions overlays as a separate option that combine with decals? How do they work, what do they do?

Just guessing, but they're probably diffuse overlay textures.
I don't have the product but I would guess that we're talking about Diffuse Overlay.
Diffuse Overlay is very easy to use. You can try this free Diffuse Overlay product: http://shop.aprilsvanity.com/flo-makeup-for-genesis-8-females.html
An overlay becomes part of the surface texture. A decal is projected onto the surface, and does not necessarily follow surface movements.
