I find it very strange that the GP felt the need to correct a difference between leading and winning. If you're at the front of the pack in a race, you are both leading the pack and winning the race.
If your team has more points than the other team, you are both leading the contest and winning the contest.
It is a distinction without a difference.
The elephant in the room, and where the analogy breaks down, is that a race has an end, the finish line. A sports match has a victory condition of some type. Nobody has a damn clue as to the victory condition of this hyperscalar craze. Anyone who says otherwise is incorrect.
GP here, leading and winning are different things in the race context/metaphor.
In foot/cycling races there's often a pack leader, that leader is often not the winner of the race, all they're doing is taking the brunt of the air resistance while everyone else slipstreams behind. For a casual observer it seems that the pack leader will win, but everyone knows that it's gonna be someone that paced themselves that's going to overtake the first spot at the tail end of the race.
