What is the intended function of Warg's Fang?

Drac is one of my main killers and when I play him I play exclusively in Wolf form.

I noticed a while back that his Warg's Fang add-on gave aura read on all survivors you had picked up a scent orb for, for the rest of the trial, every time your pounce went off cooldown. So basically any time I needed to find survivors I'd just pounce in place and run around waiting for the cooldown to wear off at which point I'd see all survivor auras (as long as I had sniffed their orbs once during the trial).

This seemed a bit strong but I thought that since it had a few needed things for set up (sniffa, being in wolf form, and having used pounce) it was still kinda fair and just a power that builds throughout the trial.

Now it seems to be back to how I remember it, where you only see the aura of the survivors you picked up scent obs from since your last pounce, making it a pretty lackluster add-on with all that set up. There was also no mention of this change in the patch notes.

The add-on says:
"While in Wolf Form , whenever the Pounce attack becomes available, you benefit from the following effect:

• The Auras of all Survivors whose Scent Orbs you have collected are revealed to you for 5 seconds."

Which to me sounds like the the first thing is the intended function, but perk/add-on descriptions can be confusing at times.

So which is the intended effect?
