Insurance coverage question?

I was involved in a three car accident, the car that started it came in to main street and got hit by one car, consequently he lost control of his car went across the next lane and hit me. His insurance already told me they are taking liability and will pay both drivers' damages, but he said that California minimum liability is only $5000, so they are planning to divide the $5000 to cover both drivers. However the damage in my car and the other guy's car exceeds $5000. I thought the limit if indeed is $5000 it should be $5000 for each driver and not for both. What do you think? Maybe they're just giving my the short end of the stick or twisting things for their convenience. Anybody knows for sure how it should work?
