That does two things that are bad. The most noticeable is that a "light touch" to the shoulder allows the rifle to get closer to its full recoil velocity, resulting in a harder rap to the shoulder.
Second, the body is part of the rifle system, and the weight of the shoulder affects muzzle jump.
That's why precision shooters always go for a tight buttstock to shoulder weld. Using the classic military sling makes that weld even tighter.
