Sure, and if there was a policy of no sexual harassment including openly watching porn, wearing sexually explicit apparel, or discussing your active sex life and a policy of no using your employer's internet for personal matters other than direct communication with family and friends, especially calling out watching porn, pirating digital media, or playing videogames as examples, that would be one thing. It's having an explicit, naked, unadorned policy specifically stating "Don't watch porn on company time" not in the context of an umbrella policy that's strange. Much like having an aside "Also don't start a fight club please" or "By the way, don't stuff your bag full of office supplies" would be weird.
