Why is movement input vector not in 0 - 1 range

I noticed that the maximal vector length of ‘MovementInputVector’ isn’t 1 but 2 instead.

Why isn’t it in the 0 - 1 range, which would be more convenient?

because it spans -1 to +1

But I don’t have an input vector going from -1 to 1. My vector goes from 0 to 1, thus it can’t have a length of 2.
