the brake master cylinder only pushes a small amount of fluid into the caliper with each stroke of the lever. about a quarter of that hose in that photo. the extra fluid in the reservoir is for a few different reasons, the biggest being redundancy. if you get a small leak, you have extra fluid so your brakes will work for a little longer so you can actually stop the vehicle to fix the leak.
race bikes are typically maintained extremely well so something like a brake line leak due to old hoses or something typically will just not happen. and so extra fluid is not needed, or wanted because of its extra weight. most racers also don't use their rear brakes very much.
plus it looks ****ing ****. i mean look at that. even blue fluid.
