I'm guessing the vet thinks 3 days is long enough for a dog to suffer before he begins to get into significant stress from ongoing acute pain and if no significant improvement takes place by then, the quickest way to prevent more suffering is to surgically fix the problem and start recovery. But that's just a guess.
Vets are used to call-backs from anxious parents needing more information anytime there is a significant injury and potential surgery ahead so why don't you just call him and find out the significance of the 3 days and then surgery if no improvement and why not wait longer, etc. ?
