I had always thougth it was also a clearance issue. The 2-pc has the primary shaft level to the chassis and the secondary tilts downward to the rear axle. This set up would have more clearance than a 1-pc shaft that tilts downward from the tranny to the rear axle. If the wheelbase is small enough the difference in clearance is negligible, but as the wheel base increases it becomes a ground clearance issue with the driveshaft. Aside from what has been mentioned in previous posts. I could be wrong, it wouldn't be the first time.
Just my $0.02
