They tighten the lug nuts in a star pattern and then go back over them in a ring pattern. This ensure all lug nuts are secure and nothing was missed. I would never use an impact or any other tool to tighten lug nuts or bolts. I have had dealers strip my lug nuts and ruin my stud and it took way more torque than it should have, never said a word about it until we had to take the wheel off. The dealer obviously used an impact wrench.
