I guessed it would work with fall damage because it doesn't indicate that the manner in which your health has to drop below 20% (i.e. from an attacker).
So here is the log lines from this.
Now how this actually ended up working in practice is very interesting. For a fall the max amount of damage you can take is equal to your current max HP. In this case I had 5606 HP. So when I hit the ground I should have died, but what really happened is that Vigilance kicked in and actually ignored the damage that would have pushed me below 20%. It then applied the heal. This resulted in me taking a net amount of damage of 1,891.

If Vigilance didn't have the heal, I would have landed with exactly 20% of my HP (1122 HP). This is very interesting and significantly different from the explanation that zinbik provided. He said that you could take 1 million dmg and you would live with 1 HP + the amount healed by Vigilance. This compares to my test which resulted in my having 20% max HP + amount healed. That is a huge difference in the function of the ability. So I'm hoping that zinbik misspoke with his explanation, though I would bet on this being a bug.
I'll get more testing with actual incoming damage and post back here.
oh yeah, hey zinbik, if this is a bug, just leave it alone man. This ability is way better this way.
*Edit* Also, if you apply the ability when the target is below 20% it will just automatically heal them and go away. So it's not really that great as an 'oh crap' CD, it's more of an 'I know bad **** is coming' CD.
