It doesn't matter (in engineering terms) whether stuff that reaches the
event horizon goes somewhere else or not (that's kind of the definition of
an event horizon). But an accretion disk outside the Schwarzschild radius
is just standard dynamics for any super-condensed object. At a distance of
several Schwarzschild radii, Newtonian physics will be reasonably accurate
(albeit not in detail).
