Putting your wood in bundles for winter is the correct way to arrange it. You want to make sure you organize all of your wood before winter comes, or the loose logs could get blown away in the first winter storm.
Right after you've finished arranging the bundles, you take out your saber (せい) and do one final slice. All of the bundles are now perfectly organized AND cut.
