What is most likely the authors point in including the following metaphor?

To furthermore insist that the metaphor given to the subject is completely true. For example, " He is a giraffe " . In this sentence its a metaphor case while if its a simile case it goes like " He is as tall as a giraffe " or " He is like a giraffe " so it just basically gives out that the description of the noun " He " is 100% given to him, like it just fully fits the character its given to unlike in simile's it may be close to the description, similar to our example saying " Like " or " as " clearly shows that he isn't completely a giraffe in height. While in a metaphor he is truly a giraffe because his height is extraordinary. In conclusion, I think that using a metaphor rather than a simile shows that the description is stronger than to be described as a simile.
