A lot of modern transmissions won't allow that. They won't make a downshift that will damage the trans. It will neutral out or stay in it's current gear.
At that speed, if thrown into park, at best it would just strip out the pawl and gear.
Ding, Ding, Ding, the truck in the original photo looked to be a newer Duramax which would have had an allison transmission. Throwing it in park at anything above 10MPH or so would have gotten you a "Ding" from the truck and a message in the odometer window saying, "Range Shift Inhibited" I own one.
