Maybe so, but he's definitely just messing around. If for no other reason then because of this sentence:

...Hobbit, which is apparently a prequel to "LOTR". This would be fine, but why didn't he just write this book first to begin with?
What kind of a critic is that in regards to the topic he's discussing? Making a prequel and not a sequel? What does that have to do with Potter or even anything? Nothing, other than the obvious messing around with people because, obviously, Hobbit was written first.
