I am not sure what Roy will say, but I would say that is an intermediate step in learning to read well, and is probably unavoidable. The problem here is that when you see an unfamiliar pattern, you will struggle to play it. Ideally, you can read difficult parts, without looking at your hands at all.
I think that you will grow out of the pattern thing in time. I am not sure though. I have been reading music for 20 years, have a degree in classical studies, and find that I can read most things well, except for syncopated rhythm patterns. Roy had me get the Standing in the Shadows of Motown book, which has done wonders for my rhythmic reading skills. This had the added benefit of exposing me to the wonder that was James Jamerson of which I was mostly ingnorant, prior to.
I am now learning to read something new, and I think I am also seeing it as patterns like you are Eminent, but I hope to grow out of that soon!
