One thing I did notice is that my arms would twist ever so slightly while benching. They would turn so that the DB's were closer to, but not completely, sideways to my body. (Kinda like you would hold them for fly's, but not completely parallel.) They naturally moved that way.
I make a point of rotating the dbs so they are parallel at the top of the lift...it's great for a squeeze.
