When a person is compared with another in learning, generosity and humility, the three qualities are independently intended. Each resemblance can be tested separately. This is multiplicity of points.
By contrast, a white cluster shining at a particular position against a dark surface produces an abstracted configuration that is not merely whiteness, darkness or spatial arrangement on its own. The intended likeness is the complete pattern.
A practical test is to remove one component. Does only one independent quality disappear, or does the overall resemblance change its nature? The former indicates multiple points; the latter a composite point.
