Orientation of the Uranian satellites

NOTE: Explaining why the Uranian satellites have equatorial prograde orbits despite the large planetary obliquity

Explaining the current orbital configuration of the Uranian regular satellites (prograde, near-equatorial orbits) in the scenario where Uranus acquired its current 98 obliquity via a giant collision. Apparently it works if the collision produces a fairly massive disc close-in to the planet, provided Uranus already had a non-zero obliquity before the collision.
