I think he knows that if he says all the things then something among them will likely appease each individual who is seeking to be appeased, contradictions be damned. He also knows that there's nothing he can say to appease people who see through him, so he just skips on his merry way. It's kind of like the shipping bouncy castle of hell. Joss built quite a little merry-go-round of the damned when it comes to shipping. You have groups X and Y, and Group X gets a lot of lip-service and attention, which makes Group Y mad because they want some attention too, so the writer gives tiny breadcrumbs to Group Y. Writer has taken Group X's ship to a point where the ship gets dashed on the rocks and reefs, so he turns to Group Y. Suddenly, it's raining flower petals during interviews and there's a lot of wink-wink-nudge-nudge-"if you want to interpret what I'm saying as promise that your ship is going to soar like an eagle, then that's your problem not mine." Group Y is happy, but now Group X is angry. In the end, both groups will feel used... until they get promised that their ship might happen after all. Rinse, repeat, ad nauseum.
