while the brachioradial group has a split going along it that kind of makes it two muscles, it's not both, the bottom muscles is just the extensor group, and the extensor group almost "tucks" under the brachial group. It's kind of weird to explain but hope this clarifies it. Also, the "ridge" is caused by that same brachial group because of it's attachment point, which is right in the middle of the humerus and snugs in between the bicep, triceps, and the brachialis.
