It sounds like they're using their software to avoid right turns where possible, but not banning them completely. I worked as a temp driver for FedEx Home Delivery a couple winters ago and they had software map out your routes. It wasn't perfect, but gererally ok. For example, I'd find more efficient ways to deliver in quiet neighborhoods where stopping and crossing the street to a house on the left side was no problem, although the software was set up to avoid that.
