There's the hard event horizon and then there's multiple radii past it with different effects on orbits (such as the photon orbit radius, stable circular orbit radius, etc) and if you're very close you're also dealing with "weaker" horizons like a radius where most light gets redshifted past visibility even if mass can still escape if it's fast enough.
