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.
