I find that assertion odd, because it works exactly as I did assume. Though, to be fair, I'm not thinking in the scientific notion that the author may.

If we think of a second as a tick of some amount of time, it makes sense to just count up once each tick. That scientists inject a second here or there wouldn't interfere with such logic.

All of that said, the leap second is going away anyways, so hopefully whatever replaces it is less troublesome.
