Temo, the picture of the creed in your first post shows a dash between the "No" and the rest of the number. I'm not talking about the underscore under the lower-case letter "o" but the dash right after that - that dash isn't supposed to be there. But that could be just a mistake at the plant.
If the style numbers aren't the same then they're different bags. If there's only one number difference then one is a smaller version of the other one so it's very possible one would have a rear pocket and the other wouldn't.
The drilldown is a search feature on the
Coach site that will find about 50 percent of the recent Coach styles. Use this URL and just change the numbers after "drilldown2/" to the style number of the item.
