Remember that even though he's an "astronomer", he's trying to sell his new book on the search for planets. How many people are going to pick it up if in the press release he's all "oh well maybe there's 1 habitable planet for every couple thousand sun-like stars". He's not LYING in saying there could be 1 per sun-like star, but that's probably at the extreme upper range of probabilities.
