Why are all Saturn’s rings located inside the Roche lobe (R = 2.4Rsat)?

The rings of Saturn could have been formed from the material of the satellite that fell into this cavity and was destroyed by the action of the planet. Rings can also consist of protoplanetary matter, which has not condensed into a discrete large body.
