I like to write. I'm not a great writer, and I'm certainly not a professional writer, but I like to write, and I like to read about writing. Not the English teacher asking what was the author trying to say here?, which can drive me crazy, or you should use the present pluperfect; it adds dynamic realism, which I regard as pompous, but real writers talking about how they do what they do, what works, what doesn't. And when you add in that they're writing for a recurring television show, it can be pretty amazing reading to find out that they are, in fact, bright, involved, and seriously creative people. I enjoy reading about things like that.
As in this case.
