What is the real significance of horizontal versus vertical fiber orientation?
Typically roots tend to spread out more in a horizontal fiber which can be very helpful under stress conditions. Conversely roots tend to go right to the bottom of the bag with vertical fiber slabs. Manufacturers who make very low-density products will sometimes recommend that their customers use vertical fiber slabs to avoid breakdown (and breakage) of the slabs during normal use.
