The traditional method in the article looks a bit different from how I learned it, which was this way https://www.wikihow.com/Do-Double-Digit-Multiplication,

The overall description of it looks right, but in the picture the order of operations would be more like B, C, D, A not A, B, C, D

Yeah, that's a bit nonstandard order but multiplication, of course, is associative and commutative, so it doesn't really matter.

Indeed—the advantage of doing it as you describe is that each new multiplication gives you a new digit that can be recorded immediately, rather than having to record the '2' from the 2 x 6 multiplication and later amend it to '5'.
