All three recognized a foul at the same time and whistled. L has a foul on A34, C and T have a foul on B34. That makes this a double foul. C and T dropped the ball by failing to report their foul on B34.

There is no dead ball foul in this play. That's an afterthought by tref to try and cover his mistake.

I'm not going to dispute your final point, but consider this slightly different situation;
B1 blocking out A1 for a rebound. A1 pushes through B1 and gets the ball. In retaliation, B1 clears out an airborne A1, knocking him to the floor.
Whistle blows as A1 is falling to the floor.
Isn't B1's foul a technical?
