One might argue thus: "The speaker modifies the hearer's auditory organ only for the purpose of cognition [of a particular sound], therefore that organ would cause the apprehension of that sound alone, not others." To this [the author] responds with the jar example and so forth. "It does not fail to apprehend" means "it does indeed apprehend," because the spatial suitability is the same—this is the intended meaning.
