Maybe I misunderstood your question.
I thought you meant if you were in the 1st and short screen, and then clicked "load recommended", would it only make changes to the 1st and short settings.
The answer to that is no, it would change everything (all down / distance options).
However, if the question is does it apply the same percentages to every down / distance, the answer is no. It does choose different percentages for down / distance / field position.
Hope that helps.
