Calculation of displacement

Hi,
When I read the code, I was confused about the calculation of displacement "tf.sigmoid(net) * FLAGS.range_max * 2 - FLAGS.range_max".
Why do we need to subtract the maximum of length?

I seem to understand this formulation.
it maps [0,1] to [-max_length, max_length].
