Brackets are used to include supplemental information without interrupting the flow of the text. They are used to clarify or explain a part of the sentence that is not present, especially in a direct quotation. They can explain quotes that are separated from their original context. And that is the situation we have presented here. The term inside the brackets is separated from their original context, and, in order for this sentence to make sense, they had to introduce it, via brackets.
