The next sentence of your last paragraph says:
> Sellers are able to choose whether to share identical inventory or not.
That seems to indicate physical commingling. IIRC, avoiding commingling has an additional cost to the seller.
As far as I understand it, that just means that sellers have the option to opt in/out of the commingling program (Settings => Fulfillment by Amazon => FBA Product Barcode Preference).
Yes, there is a cost for the seller if opting out - they need to apply their own barcodes to the products in that case.
