So if he dogged it down to first and didn't try for the hit then Keith would've called it a sac?
Exactly. That's why it's ridiculous to try and use intent as a measure for scoring a sac bunt. If you bunt and move the runner then I'm scoring it a sac. I'm assuming that if you bunt with a runner on base then the intent is to move the runner, regardless of how hard you "try" to get on base. I think people get a bit too literal with the "giving yourself up" idea.
