Tucking the first end last is fair enough for the bend, but not suitable for the loop. I first made this with the loop, and that's why it got a bit more complex, but an advantage might be that the loop is made in exactly the same way. If both knots are frequently used, both manners may be learned, but I seldom use a bend. It might be more interesting for climbers, who need rock secure loops that can be loaded in any awkward way, as well as amply secure bends.
i think it may be advantageous to learn this way of tying, in order to tie the loop consistently without too much thinking. when you get the movements into your body instead of as a visual clue, it is easier to do when you cannot see what you are doing, and you also run less risk of making mistakes if you train the movements thoroughly. I think of it as a safety aspect; to get a consistent way of making the knot.
