When you say 'staggered' you mean a single row of pendants being fed off of two rows (staggered) of upright piping? If this is the case I would think it would be merely for keeping pipe size down on each BL. Instead of taking 7 pendants, for example, off of one of the lines and having a lot of 2 inch they might have tried to split it up and keep the line sizing down to 1 1/4" or 1 1/2" eliminating the need for 2".
Just my .02 cents. I've considered doing something similar to a hydraulically calc'd system I'm working on right now.
