Depends who's coding what. Since fullstack, ick, is the norm, backend coders forced to do frontend is the case that you've described. Frontend coders forced to do backend is the case in the comic.

Yeah, that’s my experience. The backend is an environment you control completely and has well-defined inputs and outputs specifically designed to be handled by machines. Front end code changes on a whim, runs who the hell knows where, and has to look good doing it.

My experience has often been that Business mostly cares about what they and their users can directly interact with (The FE) and don't really care about spending time and effort on the BE

A significant percentage of developers regard frontend dev as a branch of the Arts, and therefore not "proper" software engineering.

I once had a fresh grad Junior complain to me about being given a frontend ticket, because they wanted to be writing Real Code and apparently thought they were too good to learn how to change the margin on a div.

I recently joined a team that had no backender for a year and the frontenders maintained the backend. In this case the image totally applies.
