It’s more complex and more generous than that.There is no rule anywhere about your height relative to the launch point.
All height rules are based on the drone's height above the ground below it.
Assuming this site is correct. See link below at end of post. If you climb a 1000 ft tower and launch the Drone, you are now immediately at 1000ft above the ground. You are free to fly to 1400ft if you stay within 400ft radius of the 1000ft tower.
It’s common sense because planes will make sure they are well above that 1000ft tower for a good distance. You can fly in that envelop.
I assume it’s true if you didn’t launch from the tower as well
