They're training people how to drive a bus, not necessarily route learning them.
When I first learned to drive a car, I was taken to some very quiet roads so I could get used to operating the machine, before being introduced to more and more typical roads. I can't imagine it'll be any different for buses; they're just looking for roads to give the learner some experience.
