As in, AFTER the production staff have done everything NOT BEFORE WHEN EVERYTHING IS BEING DONE! We've been over this exact same misunderstanding where you post the image that proves you wrong without understanding what you're talking about.
Let's try this again and if you tard out this time, I'm done.
Being a leader does not mean doing everything.
When you go to the store is the store manager (a director) working every register, moving every box, and stocking every shelf? Does that make any sense?
No, because they oversee, they do not do anything in the store's functioning besides administration unless specifically needed to do something. (a store manager may assist with a customer or other functions but will never be the driving force. Hence Yajima has story boarded episodes but has never written a single one)
SO WHY THE FUCK DO YOU THINK AN ANIME DIRECTOR DOES EVERYONE ELSE'S JOB WHILE POSTING AN IMAGE THAT PROVES YOU WRONG!?
