Generally speaking, you are correct. If I or one of my team members were to write a function similar to the one Greg pointed out, we would have used a return statement and made the function of type unsigned char. However, Innovation FIRST tries to give a wide variety of examples in the default code to facilitate teams in developing their own code. This example will help some people see the syntax of a pointer in code, or help them understand one of the trickier programming topics. In most cases, you want to avoid pointers when possible.
