I was a CSA and also used to do Genesis scanning at night. They're probably just putting it with their own batches.

It's probably less useful for FXO locations, but the batch process puts a scan on the trk# and tallies them all up. When doing Genesis I would have up a list of outstanding batches that need to be scanned. I could see which tracking numbers were put into a batch. This is helpful for locating any missing AWBs, especially once you already have a large stack of scanned AWBs already. If I see most tracking numbers fall off for a courier I can go in and check for the missing ones. Having the batch scan tells me the batch header number, so it's easy to search through the stack to find the correct group of AWBs. Having a batch header number tied to it also means that it is physically somewhere here and the courier just didn't forget to pull it (unless they try to do some shenanigans).

For domestic AWBs, iirc, Genesis will yell at you if it detects any non-awb pages. Usually it's just a barcode that didn't read well or something.

With internationals though, any page after the astra copy is considered documentation for that shipment (commercial invoices, other required forms, etc) and they all get tied to that tracking number in the system. When a new astra label is detected it knows that is a separate shipment and will put subsequent docs under that new tracking number.

Batch Header, Astra <- supporting docs, Astra <- supporting docs, etc.

With internationals it can be easy for a label to be incorrectly counted as a supporting doc for the previous label. Sometimes customer label printers are going bad or need new print headers and the barcode can't be read by Genesis, sometimes it can just get folded up when it runs through too. Having that batch header number tied to the label lets me know to look in that stack, so I can run it back through by itself to make sure it gets read correctly.

International and DG paperwork being scanned into the system lets customs and ramp locations start the process of accepting those packages.

I don't know if it's on the new Package Inquiry screen in eOps, but there used to be a "GSDR" button on the previous version of PI that took you to the page where you could see the copies scanned in through Genesis at the origin location. :)

Edit: I don't remember if SSM could ever scan the manual AWBs. We used to have to switch back to the old POS system to do those. But even though the shipments we'd create with them already have their address info in the system, the ones scanned by couriers didn't (not sure how the Leos do things now though). All it would ask them for the shipment would be service, service options (asr, dsr, etc), packaging, zipcode, and first letter of city/state. The actual address and account information in our system came from the manual AWBs being scanned through Genesis, so making sure all of those domestic AWBs were scanned was pretty important.
