The Doctor and Oblivious

I recently discovered that the Doctor's Static Blast can affect Oblivious survivors. As I understand it the Doctor's terror radius determines Static Blast's range, not its effectiveness. However there's one point I'm unclear on.

The description of the Doctor's powers says Shock Therapy and Static Blast immediately negate the Oblivious effect. I took that to mean that an Oblivious Survivor hit by a shock loses the Oblivious status. The wiki seems to agree.

However when I tested it in customs, that's not what happened. In hindsight I didn't check Shock Therapy but when I used Static Blast on a Survivor that was Oblivious due to Hysteria, the status remained in effect. This was also true of a Survivor afflicted by Hex: Plaything, but that I expected, since the Oblivious is enforced by the Hex in that case.

My question: Not counting Plaything, are the Doctor's shocks supposed to remove Oblivious on hit, and what I've seen isn't meant to happen? Or does "immediately negates the Oblivious effect" simply means it works on Oblivious survivors.

I love the idea of using a build centered on this but I don't want to be using an exploit (as opposed to a loophole/exception like Plaything).

Edit to Add: After testing in Customs I can confirm that the above applies to all sources of Oblivious the Doctor has access to (specifically Hexes Plaything & Retribution, Hysteria, Deathbound, and Nemesis). In all cases I used a custom using a Survivor on my steam version and the Doctor on my PS4 version, got the Survivor oblivious, and used both Shock Therapy and Static Blast. In all cases the Survivor was affected and did not lose Oblivious to either.
