That wasn’t the point. The point was that the manuever Anakin was about to try was foolish against an opponent at a higher elevation whose reflexes are plenty fast enough to negate whatever advantage of speed you have as a magical space knight. Anakin felt that with the “greater” power of the Dark Side he could jump high and fast enough to negate the terrain advantage, but he was being a rash idiot.
Kenobi’s clear head, as it often does throughout the franchise, allows him to see exactly what the right path is, and he knows he’s gonna wreck Anakin’s whole shizz if he tries it.
Not because the high ground always wins, but because it gives him the very clear and significant advantage in that specific situation. He doesn’t say, “Give up, I have the high ground.” He says, “Don’t try it.” Referring you the maneuver.
You're reading a lot into a very short line. That's what I call rationalization.
