No. her pre-emptive revive on death part of her the lower function of her passive ability. That's what we are talking about. And auto or not. It's broken. Please don't ignore this. It has been broken for a while and needs to be fixed.

Just punched up the numbers (limited approach) forget her passive, either booked and/or not booked, and with or without masteries Godseeker Aniri does not match up to the healing she is supposed to put out.  I really hate I figured this out after fully booking her.  But her feeling seems to cap around 6.6% on her A1 and 20.78% on her A2.  This was truly a let down.

I can't do math to save my life, but I believe (hope I'm right on this one) that the % increases to healing only add x% of the base %. So lets take her A2

Attacks all enemies. Heal all allies by 15% of their MAX HP, then decreases the duration of all buffs on all enemies by 1 turn and increases the duration of all buffs on all allies by 1 turn.
Level 2: Heal +5%
Level 3: Heal +5%
Level 4: Heal +5%
Level 5: Heal +5% 

That means with each level it's adding 5% of the original 15%, and NOT adding it like so: 15%+5%=20%+5%=25%. 

So her healing works out the way it should as far as I'm aware. 

And if I'm wrong, I do apologize. 

Yes, I just noticed this in the arena.  Opponent's Deliana killed my Elhain with her A1, but the passive revive did not occur.  Team order: X, Aniri, Elhain, X.
