I knew that you meant also. Just the wording can be very confusing.
Most pitchers throw high 3/4 anyway, very few actually throw straight over the top at 12 o’clock. Nomo, Lincecum, Santana, Clemens (when he was younger), and Koufax, to name a few.
If any pitcher is going to use an overhand release point, they should understand that it’s not about “getting the elbow up”. It’s about shoulder tilt, which is controlled by the muscles of the torso. Don’t use the muscles in your arm to “raise” your arm slot.
This is how NOT to raise your arm slot:
Another thing with the overhand slot you will notice is that some pitchers have a slight lean backwards before their front foot plants.
