They don't counter each other. At that dose, it's only going to be acting as a sedative (H1 blocking, alpha1 blocking). The alpha2 blocking could have adjunctive antidepressant effects by disinhibiting serotonergic neurons, but Seroquel's 6 hr half-life means it won't be around in the daytime. The only other thing it does at that dose is block 5-HT6, which is anxiolytic in animal models and might help you get to bed easier.
