Yes. They can mean both “a” and “b.” They clearly mean “a,” but certainly “b” would be implied in most cases.

“B” becomes a question of logic, but in everyday speech the cause-effect relationship would probably be understood though it is not explicitly stated.

In formal writing or in a formal situation like testifying in a lawsuit, you would want to be more direct as in “b.”
