What does this mean: "where one side has at most one edge"?

A "local" point corresponds to at most one "global" point. Suppose we have scatter between spaces {a,b,c,d} and {x,y,z}. An example of a valid scatter is Scatter1 = {(a,y),(b,z),(c,y)} This is entirely useful, but I don't know if the following is useful: Scatter2 = {(b,y),(b,z),(c,y)} Is anyone using scatters that look like Scatter2? For what purpose?
