In Commas^x, Predicates^x

I heard that you were into artificial intelligence, and thought that you might have sent me the packet. In the sentence above, would the use of breakign the double predicate rule - i.e., adding a comma 'and' - be considred OK. I think that the comma helps keep the sentence less ambiguous....

I read somewhere that you should not but a comma before and when it acts as a double predicate. Could someone please show me a few examples of what this is. Thank you.
