A simple single point is one intended quality not analysed into independent aspects. Radiance in “a face is like the moon in brightness” is an example.
A point treated as one is a composite scene whose parts combine into one intended arrangement. Removing one element changes the image. Multiple points are separately intended common features, each capable of functioning on its own.
Compare:
“A scholar resembles his teacher in knowledge and forbearance” — two distinct points.
“A pattern of scattered lights resembles stars in a dark sky” — a unified configuration.
The key issue is not the number of descriptive words but whether the intended resemblance is one organised form or separate comparisons.
