Lip curls can mean lots of things. My puppy does it to a dog that doesn't like him that he has bad history with. He never goes any further.
If a dog was going it while it had a ball in it's mouth to another dog, it likely meant that he WANTED that ball, and was resource guarding it. Get the other dog away PRONTO, or a fight COULD occur. It's never good behavior; some dogs will attack another dog over a toy, some just growl or lip curl, some don't care about the toys.
