I think you’re right. It reminds me of some of the awful jokes I’ve heard about medical professionals like EMTs making.

Any morbid job seems to lead to morbid humor as one coping mechanism. And it’s not intended to be a personal insult because you’re not a person to them when they encounter you as part of a job routine, you’re a task. Tasks are something people are inclined to joke about. That’s just how brains work and doesn’t make people evil.

Doing it while on camera is monumentally stupid though.
