Yes, he's sure. With the current technologies it is impossible to fit more mAh's into the same size without compromising the quality of materials used. This may mean the first few charges a 'bigger' battery may be more effective, but it will decay so fast, that it definitely won't be worth your money. If you want to extend your battery life, you will either need an extended battery double the size or you'll just need to carry a spare one with you.
