Seems there were trying to do find a vendor which would do an open-source implementation of the end-to-end verifiable STAR-Vote system, but couldn't find a vendor last year who was willing to open-source the code. So the country instead went with a vendor which while maybe not as good as STAR-Vote, it still would at least produce a verifiable paper trail, and they will do statistical audits of the electronic vote with the paper copies so could be reasonably sure the electronic count was not tampered.
