dilla's pattern may not fit the beat exactly but is still a pattern.
if you had the acapella to the song, you could re-blend with the instrumental in a way that was more "normal" but it would loose its swagger which comes from crazy swing of his rapping rythm.

it also helps to sound confident when you're rhyming "off beat".
detroit emcees got that style mastered aka rhyming in front of the snare.
