Looks to me like a Green Card job. They wanted the job for an internal candidate and so they crafted in a way that only that candidate would meet it. The law requires them to advertise in a public newspaper of record or some such thing.
They can only really reject you for lack of qualifications for such a job ad by law so that's probably what happened. If it was open for a while, they probably have a few internal candidates they needed it for.
