How doesn't it match up?
You can edit what certain plays you want in certain situations, meaning you can have more than one 3rd and short play, 2nd and long play, 1st and 10 play. But its up to the coordinator to decide which play you have to execute.
A more passing type of Offensive coach might want you to go for a play action on 3rd and short to fool the D. So instead of that halfback dive you put in your gameplan for 3rd and short situations, he might run the play action you put in their (if you happened to put one in). They're not going to call a play you didn't put in your gameplan, unless your using the teams plays
