How is it odd? Warner, Disney and Lucasfilm don’t communicate constantly.
Lucasfilm must’ve gotten in touch with Disney/Warner that he had contacted them must’ve pulled some strings. He should be really grateful, and I’m glad he is actually thanking Lucasfilm for a change. Hopefully this will help stop people from lumping Disney and Lucasfilm together constantly, but who knows.
EDIT: The more and more I read YouTube comments the more I realize it is mostly literal children and I’m wasting my time thinking about this so much.
