Your record is clean, because they are baseing your pending removal on his FBI number. It will show up on his record and they think he is you. When they finally get ready to deport him (you) they will upload the information to the FBI to show the removal. They will also be uploading "your" A-number in the data. They might not add a record of his pending removal until they take custody of him years from now.
You only get one name and date of birth when they create a FBI record, then they add alias to it. Once again, your record is clean because they are not searching the right one, but that doesn't help your immigration status.
You need to get on the telephone and call the Office of the District Consul at your local ICE office, they can fix the mistake or contact your local US Congressman's office for help.
