Yes, you have to watch every package to make sure it's not yours, assuming the splitter is a good splitter most of your stuff will be on the correct side of the belt, if the guy above you is a good loader he won't let stuff go past him, if he sucks, your digging through his packages and yours, you also have to either toss his to him or put them on a cart for recirculating if he misses them, it's hell to load 5 cars and catch all of the new guys stuff too. It typically results in cussing one another once you've had enough of it.
