True statement. However...it's still legal. Flying formation with another aircraft without prior arrangement is an FAR violation, and presumably frowned upon by the DoD also.
Exception would be an intercept of course, but conducting an unauthorized DITY intercept of a civilian airplane in this day-and-age is an obvious no-no. The pilot probably thought he was getting a real intercept, no wonder the viper guy got spanked.
