No they don't, they count as seperate damage sources. They also will not trigger Rylai's Slow.

The only thing they get from him is his AP (Their AP power is set when placed, so if you upgrade your AP, you need to place a new one to see the damage increase) and his Magic Penetration (they get the benefit of his magic penetration as soon as he gets it, so you will see an immediate damage increase)
