I agree. I do not care for this method as it is just a method, not promoting understanding. Even an intuitive explanation of why is works would be great for beginning algebra students, otherwise it just turns into something to memorize like a recipe. The common called "trial and error" method promotes number sense and students see what's happening. Once students develop good number sense there is much less random trials of pairs of numbers.
