No, it just means that Fox would be making money for Comcast/Universal via producing X-Men movies as long they produce them within a certain period of time. Remember the royalties that Marvel makes off from its licensing agreement to Fox for X-Men is peanuts in comparison to the BO market share Fox makes; it's the reason why Marvel have merchandising, video game, and cartoon embargo on the Fantastic Four and X-Men, because they don't want to be seen promoting a major competitor. So if that happens, then it would involve more tensions and heat between Disney/Marvel and Comcast/NBCUniversal, rather than Fox.
