yeah guess ya kinda have to see ds, kinda hard to describe. basically the spinner is deliberatley smaller than motor tube so that air around it can pass into tube rather than shrouding over the motor tube stream lining it. and i see what your saying about duct diverging, but that usually only a problem when it does it on its own. In a properly made duct where it diverges in unison with spinner, the air doesnt know its diverging cause as it goes out spinner is also pushing air out in same ratio. so air see's same size path, and long as its not real sharp it wont seperate.
