I can find nothing in the Laws to indicate that replacing the call oneself before the director has ruled is an irregularity. It should be, of course, but 28C does not state that is. I think the irregularity was the IB, and that this entitles anyone to call the TD. And I don't agree that calling the director for the only possible reason that you want North to Pass is an infraction. The director call is AI, as it arises from the legal procedures in the Laws.
Law 10C2 said:
If a player has an option after an irregularity, he must make his selection without consulting partner.
This implies that the partner to a player who has options available after an irregularity may not in any way convey any kind of information that can possibly suggest an option that might be preferable to their side.
This even includes information from the manner in which the Director is called.

I would go further. It is legal to have an agreement that South calls the director if he wants his partner to accept the IB, and does not do so if he wants North not to accept the IB. Except in a jurisdiction where you are not allowed to vary your agreements consequent upon an opponent's irregularity. It is a bit like when declarer leads from the wrong hand. My partner and I pause to see out if the other wants to accept the lead.
Here North can also accept the substituted Pass and the only LA for East is a diamond lead, when 3H is cold.
I consider this part of your comment to be evidence of a deliberate and serious laws infraction.
Your agreement about calling or not calling the director depending on whether you want to have the IB accepted, and your agreement about hesitation when declarer leads from the wrong hand are severe violations of the prohibition against concealed partnership understandings (You don't explicitly declare it in advance do you?) in addition to violations of several other laws.
