Toss up? Obstruction and Interference on same play

Big Tex - given your scenario - when did the ball become dead? According to FED in OBS, it's a delayed dead ball and the play is not killed until all playing action has stopped, then time is called and bases awarded. See example from CB 8.3.2 Situation A

RULING: Umpire shall signal a delayed dead ball when the infraction by F5 occurs. At the conclusion of playing action, he declares the ball dead, then awards home to R1 and allows R2 to remain at third.

The play is not the same, but the mechanics of calling DDB should be. Thoughts, anyone?
