Ooh! I'm great!
But anyway, Rock: if you are looking at pictures and seeing the that the muscles ride higher or lower on the inside or outside of the leg, then by all means you should draw that! It's those little observed details that make the drawing interesting (in my opinion). The method you describe with the muscles at the same level is just inattentive drawing. I don't think it is a style to be emulated.
My theory is that it takes a long time to learn about every single muscle on the body, to the point that you can draw without references. For myself, in each new art I do, I often pick a small group of muscle to study.
This is a really helpful idea for sharpening anatomy skills.
