You’re missing that there is a difference between the Q store core and the name embedded major.
The 1st option will give you the same version as the regular Major Program plus the module with Name embedding.
The 2nd option will you a name embedded version that is not the Major Program. My understanding of the Core Q-store modules is that they do not contain all of the elements of the major store titles. Instead, they are a pared down version that you would have to add modules to get the full scripting of the Major Title.
This new service allows you to bypass all the decisions for up to 20 modules and get an original Major Program as the creators intended with your name embedded and in this case up to one module to enhance the major.
