When should I use uv1 instead of uv0 in Unity Standard shader

Question

I am wondering when to use different parameters UV Setin the Unity Standard shader.

I know that UV means texture coordinates, but why should I switch to uv1instead uv0? I don't see any immediate difference when I switch between them, and Unity docs don't seem to explain much.

Perhaps someone can shed light on when to use different sets.
