They are, indeed, quite different things. Finding the truth value of an object is not the same thing as testing if the object is equal to the object True. When people use the phrase "evaluate to True" in the context of an if: statement, they mean that the truth value of the object (found using the special method .__nonzero__()) is True, not that it is equal to True.
