I was curious about this as well and found this:

Q: How do Italy Boss Fights work? (Question added 10/14)

A: Italy Boss fights work a bit differently than Vegas Boss fights. When you start a Boss fight in Italy, a timer starts for that fight. The Boss will not heal until that timer expires, at which point he will completely heal. Until then, you can come back into the fight as many times as you want. Your friends will also be able to help you attack the Boss. Unlike Vegas, you will not be able to use two Boss fight consumables in a row (health kit/shiv/grenade/stun gun). Remember, once you beat the boss, the tier will be completely mastered, so if you still have jobs you want to do for the skill point, master those jobs first.

tl;dr, If you reach the boss and beat it, you automatically master all jobs on all paths, but if you didn't actually master certain jobs using your stamina or energy (such as say, skipping the fight path altogether) you won't get the skill points that come with normally mastering the job.
