Demanding Attacks and being interupted

Hi

Just been doing a bit of a re-read and found a ruling that demanding actions are interruptible.

This means that when a hero does a devastating attack it is not resolved until the clock has moved 6 ticks and it can be interrupted if the hero is attacked before those ticks are up.

But my question is, how does this work for Team attack. this is a demanding action that needs to be done on the same tick of 1 tick after the initial attack. Does that mean that the damage is not added until after the 6 ticks and when can followup team attacks be made?

For example
Tick 2 – John hit zombie for 6 points. (not a wound)
Tick 3 – Brendan hits zombie with team attack for 12 points (wound)
Does zombie drop on Tick 3 or Tick 9

Example 2
Tick 2 – John hit zombie for 6 points. (not a wound)
Tick 3 – Brendan hits zombie with team attack for 12 points (Not a wound)

When can a follow up team attack (using Brendan’s damage) be made. Tick 4 or tick 10(after demanding action resolved)

Cheers
