Your experience and the explanation sounds reasonable. In this case, the former is probably more important, as each of us is slightly different. Even if there were a strong anatomic reason why more vertical than 45 deg would be "best" your body may not have read the same textbook from which the experts have learned. I'm fortunate not to have the disc issue, but when I have lower back spasms (typically with my prior job), the two things that would really make it feel better would be riding my bike or swimming. My position would be with raised bars compared to most road bikes, but still over far enough to put a nice, natural lean without having to crank my neck to see past my wheel.
