Braking question

Ok so anyone who has ridden for much time has learned the valuable lesson of "if shit goes bad on a hill NEVER hit the back brake just hit the front". So how does that work on the Polaris Sportsman’s with one brake lever. If you are stalled on a hill and grab that lever are you going to flip because your back brake was initiated or not flip because it initiates both front and back brakes. Just curious.
