* Never give false options. Do not create multiple options that lead to the same result. It insults players' intelligence and does not reward them for the choices they make.
What he means is "don't give two options that look like two completely different ones, and yet come to the same conclusion". It's okay to have this:
1. Hello there, sir. Sorry to disturb you, but could you please give me the directions to the nearest pub?
2. Can you tell me where the nearest pub is?
3. Hey, shithead! Tell me where is the nearest pub or I'll make your dentist unemployed!
4. [Ask him where the nearest pub is using gestures and mimics].
All leading to the same conclusion, said in different way. It's okay, because otherwise they are putting words in the player's mouth, and it's nearly obvious that it leads to the same result. I'm not counting the entertainment value as reward for that individual case.
A several completely different actions, leading to the same result is okay to use just a few times in the game, when the story makes up for it.
