Pretty sure from his explanation the pinion is rotated up inline with the drive shaft. As I tried to explain in another post, the angle is down though. If you draw a line through the t-case, follow the driveshaft and finally through the diff the line angles down the entire way.

Here are a few pics. Visually the driveshaft is phased properly but when measured with a bubble level, it is not exactly true. The yokes are a full bubble off. I don't know if this would have an impact or cause a vibration. Not sure what the tolerances are for phasing.
