It’s possible that a sufficiently good instructor could communicate just as effectively through purely verbal instruction but I’m not sure such an instructor exists.
I would suspect this has more to do with the skill of the student in translating verbal descriptions into motions. You can perfectly understand a series of motions to be executed under various conditions, without having the motor skill to assess the conditions and execute them perfectly in real-time.
