This is a great way to think about it. The "roll" was made on the loom with the warp threads parallel to the long dimension of the roll. The selvedge was made on the loom by sending the weft threads back and forth. As the weft wrapped around and went back the other way, it formed the selvedge edge that doesn't ravel. There isn't any way of weaving a piece with a selvedge parallel to the weft threads, only parallel to the warp threads. When you cut a length of fabric, you're cutting across the warp threads, and the cut edge will ravel.
