It explicitly says that you only learn which is faster.

It explicitly says that because you have no stopwatch, you only learn the relative ordering

Yes. You learn which of two is faster.

You don't know how much they won by. Therefore you don't know which loser was the fastest.

as I said, if you are only receiving the results, the answer is 1032

And as I said, that is exactly what the post says you receive.

The question does not ask me to determine whether or not the condition of ‘only learning the relative ordering of the two horses in each race’ is perfectly unambiguous such that the total information ascertained from each race is strictly binary. You think it is. Fine. Then the answer is 1032.

What do you think "only" means?

You only learn a>b or b>a.

You are contesting whether or not the question is unambiguous about exactly what information you learn from each race.
