The only thing I found strange about it was that he started from the least significant digits rather than the most. It's basically the way I've always done subtraction, just backwards.

You will also have to be careful about alignment, since in one number you start from the first digit, but in the other you may start from the middle. It's slightly more complicated than just starting from the least significant digit.
