This is just a theory, but lets say your Harden and Washington at the five spot gives you a rock solid guarantee that they will take you when thier turn comes. If your Washington you don't want him to risk injury by doing a bunch of worthless workouts. At the same time you can't preclude him from trying to move up higher if possible. So Washington puts some conditions on their promise. Interviews only, and no workouts.
Harden has a reputation as a good charactor guy. There has to be a reason he would risk offending the rest of the league.
