Dmitri has received 22 damage. He and another minion are on the board. Based on the P value Dmitri's health is 2 X 20 or 40. The minion is defeated. The P value is now 1 X 20 or 20. Is Dmitri immediately defeated because his health is now 20 and has received 22 damage?
The P value means “per fighter” in the game, not per minion. The boss’ health scales for the number of fighters in the game.
