I'd say that's a matter of lawyerism and interpretion of rules that don't state it explicitly enough. As far as I know you can only have one trait of a given type. That "type" could be interpreted as campaign/faith/religion etc. traits or..traits giving the same thing.
There's also the thing with bonuses of the same kind not stacking unless specifically noted - that in turn could be interpreted as trait bonuses not stacking..so you might have two traits giving the same bonus, but only benefitting from one at a time.
