[Star Wars] In the ROTS, did the High Ground give Obi-Wan any actual advantage in the fight vs. Anakin?

When Obi-Wan said "It's over, Anakin!" he implies that just by having the high ground he's automatically won the duel. What was so different about this instance vs. any other time in that fight?

Fighting uphill is a massive disadvantages in melee. You spend a lot of energy fighting both your enemy and gravity. Meanwhile the one on top has gravity working with him.

You always try to keep the battle at least on even ground. If not you lose all your limbs and fall into a lava flow.
