What they indicate is sweep and upsweep when the rise is set perpendicular to the ground. If you roll the bar back until the bar grip area is horizontal with no upsweep, you’ll have a bit more horizontal sweep and a touch less reach. Roll forward enough and you could eliminate all back sweep and have only upsweep. Most people run their bars with the rise perpendicular to horizontal. Listing the angles this way makes it consistent so you can compare bars. It’s important to note that there is no one correct way to run your bars. You adjust the roll to fit the rider.
