They wouldn't necessarily be the same AID but they'd be the same prefix and partial AID matching is used (Amex especially does this).
The network sets the certification standards as well as determine who is approved to certify. As far as I know, no US merchant accepts UnionPay chip cards. But the terminals deployed definitely CAN.
Now, why no one has... I have no clue. Maybe the liability isn't seen to outweigh the cost? I do know UnionPay standards are a challenge to meet.
