You're retarded. Comic artists almost always have reference in front of them. Most comic painters take photos of their models and paint from those. Do a little research on Alex Ross for examples.
Plus, comic artists "swipe" each other's page layouts and poses constantly. Every artist has their favorites that they emulate to learn from.
You haven't the slightest idea... how do I know that? Simply because I've enjoyed 3 years in an german art school and every teacher tells you the same thing over and over again, if you do not understand the human body you will not be able to draw properly, every book from Drawing the Marvel way to the best books about drawing the human body will tell you always the same thing again.
I know a lot of comic artists ~(or have known them) and I have watched them work and non need any guidance when it comes down to draw poses, there are certain poses (marvel has some very distinctive once) you will see over and over again that has nothing todo with artists copying them self, but simply because they are stylish and emphasize a certain part of the story.
Seriously don't bother explaining yourself you have no idea..
To further prove my point, and there are thousands on youtube, and none of them (some you can see the whole room

need a model)
