I know this doesn't answer your question but I found this on the description of one of the Amazon's AC Delco DexVI 5 gallon products. Different part numbers than what you list but still interesting.
********************STOP!!!!! PLEASE READ BEFORE ORDERING**************************** One of two labeled bottles may be sent. They are the SAME product made by two different manufacturers. 10-9395 or 10-9244 will be sent. Regardless of which one you receive, it is the SAME part made by one of two manufacturers for AC Delco. It is their version of lot control.
