This is due to the contract style. Lawyers frequently insert digits (14) in parenthesis in contracts to forestall any other allegation by a party to the deal that they misinterpreted the contract or that a referred number was not in the contract. These allegations can be used as a sword by either party to get out of the deal. They also do this for emphasis. If one thing is said, another might be left unsaid. Inserting digits gives the reader something to focus on besides what's being said. There are also cases where people write contradictions simply because they don't know any better. For example, if I were to write "I like blue cars" and "I like red cars", there would be no way to tell which car I like best. In such cases, inserting digits would help clarify my statement. Finally, lawyers do this with phrases like "without limitation". If a lawyer wrote "John has unlimited access to our files" they would be clear enough that John cannot be denied access to these files for any reason. However, since this phrase is written in legal language it means that even though John cannot be excluded from seeing the files, he still needs our permission to do so. If we wanted him to have complete access, he would only need to ask. In conclusion, writing contradictions is useful in some situations when clarity is needed.
