Opinion: the great strength (sic) of Velcro is its shear (parallel to the surface) resistance. If I understand right, putting the velcro on the edges would depend on pull resistance.
But wait! You also get: if you fasten two solid edges with Velcro, you have to get it to release along the whole surface at once. (Even if you get a knife-edge into it, it's going to close up along the retreating edge of the knife.) Peeling it up if it's flap-to-surface means you can work on it gradually.
