The "bending" is happening after you are "squared" in place, not before or while preparing your shot. First draw the bow like shooting straight and after all the things are in place, you bend. When the structure is in place, you will see that the single way to move without losing it, is when your eyes, head, shoulders, arms, bow and arrow are acting like one.
The cant is something that is happening due to natural position of the bow hand when properly extended, the type of grip you use and how you look at the target. Unless there are some branches or obstacles that will force you to try to avoid them to get the shot I see no reason to worry about canting - this is something personal that comes natural. Trying to mimic something natural for someone else is not a good thing - forget about others, just observe yourself or listen to your body. When it doesn't feel good, something is done wrong. Sounds like a line from Mr Obvious book, but reality says that we tend to be "monkey see, monkey do" when we learn new things instead trying to understand why we see what we see.
