The problem comes when tensioning the line with the brake off, to adjust the winch alignment or just straighten the line on the ground during use. When you let off the pedal and the drum spins backwards with a loose sleeve, the drum can actually spin faster than the sleeve...then you can end up with a real rats nest.
