If the other player was first on 1820 points (say), then you reached 1820 to check your standing, then you'll see yourself move to the top of the leaderboard... then the other player's score updates, and they 'overtake' you.
Now, if it's the case the you open the table, you're clear of the other player, then open it again and they've caught up to your EP total, and are now ahead of you in the table, then we have a bug, and you should support-ticket it, as Wizard says. But I've never come across a case a of that happens. And a bazillion of the previously described circumstance.
