Are the Moto X1 and the Nexus the same phone? The parent comment seemed to suggest that they were 2 different phones. Even in that case, what Apple released was slightly different from what AuthenTec had created at the time so I don't see how anyone can say that Touch ID was out before Apple brought it to market.
Literally the only Google results for a search regarding Authentic and the Moto X1 is this thread and your comment.
