Should Thornmail trigger turret aggression?

As you can see in this clip, Dr. Mundo had equipped Thornmail and Kindred was auto attacking him under Kindred's turret. Kindred ended up dying due to Thornmail's damage and the kill is credited under Dr. Mundo's name but due to some reasons, Dr. Mundo wasn't attacked by turret. Thornmail didn't trigger turret aggression, and Kindred just died.
People can argue how Thornmail's unique passive can only cause self-inflicted damage but if so, why is Dr. Mundo credited the kill when it should have been "exceuted" instead? I am pretty sure the death recap for Kindred would have recognized Dr. Mundo as the killer as well.
What do you guys think? Do you think it's a bug or it's something Riot has intended to do? Obviously Thornmail triggered turret aggression in 2011 but for some really strange reasons it doesn't work now?
Edit: Gromp buff, which works similarly to Thornmail's passive, actually provokes turret aggression. Champion abilities that work similarly do so as well (Annie's E and Rammus' W), so why is Thornmail an exception among all?
does so it only seems consistant
