So.. let me see if i understood this:
You trade him , (and i guess you must have just those items you are going to trade in your inventory) You Pk him , after that a friend kills you , so you drop the things you were trading and you press confirm so, you get his item and he dosnt get nothing beacuse you drop your trade?
This is Wierd , i have never thought of it xD
Gonna try and see what happend , ty buddy
Btw wrong section , this is an exploit-Scam and should be in exploit section , some mod move this and hide it (he dosnt even know how to hide xD)
