I have no idea about the process in any other state, but that is what has been done here for at least the last three elections. (Those being the ones for which I have requested an absentee ballot.)
This is the first time I ever voted absentee, but in Michigan, the number that identifies my ballot as belonging to me was on a perforated stub, visible outside the privacy envelope. In Michigan, the privacy envelope was not a sealed envelope. The stub stuck out at the top.
I don't remember exactly where I signed or exactly what I filled out, but I remember noting that you could do all of the ID of the voter without ever looking at the ballot, and then you could take off the stub, once again without looking at the ballot. I don't think I made any marks on the ballot itself except for filling in the ovals.
I'm assuming that the process involves getting the envelope. Scanning it, verifying the signature, removing the stub, and then putting the stub in one pile, and the ballot in another. At that point, there is nothing on the ballot to indicate it is mine. I assume that's what happens to ballots, but as I say, I've never been an election worker, so that might not actually be the case.
I skimmed a few seconds of Rudy's video attached to his tweet. He was going on about the poll worker asked not to verify signatures. Once again I have to wonder whether Rudy is lying or stupid. The processing of the ballots are not done that way. One station verifies the signature, and sends it to the next station, where that guy was working. He didn't verify the signature because it wasn't his job. It was someone else's, and yet Rudy is chattering about it.
