If you both made a call, and each of you thinks his call was undeniably right and you each wish to stick with it at all cost, then without a doubt you have a blarge. This is spelled out in the now famous case 4.19.8 Situation C, even though I could never have come to this conclusion by reading the rule book. But there is nothing in this case which says that a preliminary signal is binding in making this call.
