I always sew each row, then sew the rows together... but thats really because thats how I learned. I'm not actually getting the other method... how do you put a quilt together without long seams?

So I would sew 1&2, 3&4, 1+2&3+4, then 5 to make the first row. I'd do the same with the other 3 rows. I'd then sew the first and second row together and the third and fourth. Then sew the 2 double rows together.
The way I'm imaging the other way is:
1&2, 6&7, then sew those groups together. Do the same with 3&4 and 8&9. Sew 5&0 together, then add them all together. Do the same for the other two rows... you still have the middle long seam, right? It definitely reduces the long seams which is cool, but doesn't eliminate them...
Unless I totally don't get it
