They should definitely be marked if there are MM hunters DPSing them, but not IMO by the hunter with IHM. Leave his mark on the boss, so only one GCD is used to mark when an add spawns instead of 2 (one on the add and then one on the boss again because the IHM hunter marking the add would remove his mark from the boss).
Ooze variable can throw a wrench in this system though since the hunters can end up split between 2 targets.
