Showers set the temperature by mixing the (usually fairly cold) tap water and the hot water from the heater. When you’re at a middle temperature, both of those flows are running full blast, and forcing their way through your shower head. When you turn it all the way up, you just have the hot water flow, but the same shower head. Less flow through the same nozzle = less pressure.
