Classification of data object might be incorrect

Question

I am learning a new Salesforce product (Evergage) for the company I work for. In the program's documentation they have listed a set of data objects as an example. It appears to me that the classification might be incorrect. Their system makes a division between 'catalog objects' and 'profile objects' and the example they have given is a banking institution. They classified Customer Credit Card as a profile object and Credit Card Level as a catalog object. Seems to me that it should be the other way i.e Customer Credit Card = catalog object and Credit Card Level = profile object. Maybe I am not reading the context correctly?

here is a link to an image with the complete classification: https://drive.google.com/file/d/1nG4aX4Ty_NoHxm04AQo1Ow61m3MZ3pXm/view?usp=sharing
