It sounds like you pay per category per brand/logo. This specific scenario played out just after Bauer bought Easton: https://uni-watch.com/2016/11/01/corporate-theater-unfolds-on-nhl-gear/
To me it makes sense. Easton is a bundled entity that has a corporate life of its own. Even if it’s all but dead at present, it could be sold at some point. Advertising it on the biggest stage in the industry would increase its value prior to sale. The NHL doesn’t have a buy-one-get-one-free offer on the value generated by that exposure.
