Given the same kind of wind, heck yeah, it makes a difference. That pseudo-TT position I mentioned is as close as I'm going to get to a flat back on that bike, and I can sustain a higher speed for longer than if I sat upright. Try it for yourself by pivoting forward at your hips (don't just bend your spine) and crouching forward.
The rider creates the most aero drag on any bike. Duck down and it's like tossing away a sail.
