if there are no set in (Y) seams (like an under arm gusset) or partial seams it doesn't matter. The quilt in your link can be assembled any way that makes sense to you. BTW Those areas that look like white squares in the quilt are where 2 blocks with white margins butt up against each other, not a single square of white. It's all the same L block.
