That's right, any amount of alcohol reduces awareness and increases reaction time. I think what the poster meant is that while a person driving under influence might be slightly distracted (there is full spectrum of being under influence) the person fidgeting with a phone is always very distracted. You can't be only slightly distracted when you are not looking at the road but reading or replying to message.
