Thanks, I missed that. I was just looking at the number of decimal places. Is that method accurate?

(1000 * incorrectly_rounded) / 1000 == incorrectly_rounded

It's not incorrectly rounded. It's correctly rounded to two decimal places in either case. Two decimal places just isn't enough digits when you give it 1 USD, so you have to give it 1000 USD.
