The info is yet important because of how LD works. There are 2 phases: when he is with Living Dead active and with Walking Dead. Both appears on the DRK's status bars.

While it's with Living Dead buff, the healer can safely ignore him (or must resist the urge of healing the tank), because he won't die, but instead will get the Living Dead buff while he have the Living Dead buff. While he's with the Walking Dead buff, he is invincible for 10 seconds. If the DRK don't receive healing equivalent of 100% of his HP, he will die. If he does, the Walking Dead effect fades. The healer(s) must plan their actions to ignore that tank for some seconds after he gets the Walking Dead buff and top him up just before the 10th second after WD is up by any means available. It's a good idea to save the oGCD heals for that final seconds.

In that case, the healer can know by looking at the DRK's status bar. But if DRK says to the healer(s) that he will use that action, that would be a great idea, because that will one more clue to the healer(s). If after that the tank still dies, it's on the healer.
