It's actually very different. I don't know why they are called the same, but yours allow distribution

    You may use, copy, reproduce, and distribute this Software for any non-commercial purpose
    you may create derivative works of such portions of the Software and distribute the modified Software for non-commercial purposes

While the one used here explicitly deny it:

    You may not distribute or publish the software or Derivative Works.
