Hi, a) only S. Wolfram will know it, because he wrote the book b) Get[] is the older construction, and read always the package. Needs[] is bit newer and will load the package only if it not already loaded. Since Needs[] only look for the context it will not work if you try to load a edited package again Since the book is update from version to version it is no need to replace a correct working line by an equivalen one.
