As we interpret the rule it does not matter that several rounds of play have passed after the first horse has crossed the finishing line before the card is played, as long as only one horse has crossed the finishing line when the card is played.
That's more liberal than I'd be willing to play it. A photo finish in the same turn seems reasonable. A photo finish with a horse that finishes after the first horse and rider have made their way to the winner's circle? I can't see that.
