I'm not sure if this is a case of Github misidentifying the license or something, but it makes absolutely no sense to license something under BSD 3-Clause and have "All Rights Reserved". As per the first google result:
"As a copyright owner, you might use the “All rights reserved” notice to indicate that you retain all rights provided by copyright law. As such, another person cannot reproduce, distribute and/or adapt any part of the work without your permission."
BSD 3-Clause is a free license, All Rights Reserved is as nonfree as it gets.
