I have seen the same thing happen even on having 2 of these trigger off of 2 different creatures.
I have also seen it where the landfall on the second creature never triggers,
Example : Sazh's Chocobo and Tifa Lockhart both have (2) +1/+1 counters and both have the Ordeal Of Nylea Enchantment applied. And are attacking.
Ordeal Triggers for the +1+1 counters on both and then gets sacrificed on the Chocobo and I pull 2 lands. The Landfall triggers on the Chocobo.
Tifa doesn't double her Power off the 2 land fall and her Ordeal gets sacrificed but never triggers a second 2 land pull. If they are split by a turn both happen properly.
