WOW, I am either completely off my rules & judgment today or ….
1. OBS is called when it happens (at 1st in the OP), not after the effect, and never after the play.
2. The PU was wrong about
a) listening to the DC about your call
b) waiting a beat to see what happens
3) the protection between 1st & 2nd is not being put out, then an award of one or the other
4) immediate dead ball is appropriate if, and only if, a player needs immediate injury attention
5) Why is "softball, like high school baseball, treats" needed?
