Why is Lerp Alpha commented to have values 0 to 1

/** Performs a linear interpolation between two values, Alpha ranges from 0-1 */, but Lerp will work just fine with Alpha > 1, basically continuing along the line created by the two point inputs?

0 to 1 gives you the whole range from 100% A to 100%B, which is the main use of lerp. The fact that you can go outside this range, is just a side show.
