I can assure you that this statement is correct; when purchased, the two Promissory Notes lead to the two previously blocked passages being unlocked.

I will add that it isn't instant. When you leave and re-enter the Ancient Quarry, you'll find two workman near the north entrance who say something about excavation work. On returning after something like a day, the two passages should be accessible.
