Well, you can either continue to demonstrate your ignorance, or you can crack open the syllabus book and notice that bronze foxtrot has foot rise and outside partner coinciding while bronze waltz and quickstep go outside only when coming from a lowered position where the body is easily projected by a standing foot that is flat on the floor.
So what? The variance in styles does not prevent anyone from practicing all of the different movements.
You learn the moves from a competent instructor and you practice them until they are mastered.
Time on the floor is the most important aspect of any dance student's education.
