Rudra, I trust RobotLove answered your question. Like you said, having the command work as intended is good either way.
Six-Six, I am not having problems summoning my bots, only with the "cursor" functionality in powexeclocation. Indeed, while "cursor" misbehaves, I am using almost what you suggest. I don't like the bots falling directly on my head like they do with "self", so I am using "0:10". 10 feet directly in front of me is usually an okay spot.
Fira, yes, pointing has a max range originating from the character, regardless of where the camera is, which is how it should be. You can visualize a sphere centered around the character if you move the mouse around before clicking, seeing where the targeting reticle "tilts upwards" from the ground as if to hit the inner walls of a sphere. My report is that when using powexeclocation cursor, that sphere is centered on the camera, not the character. Which I suspect is unintended.
