It might also have to do with how programming was taught to a certain generation? At least from my own experience, when I was at university OOP and UML was all the rage, so we had to specify through diagrams in fancy diagram editors, then generate the code from that, and then still re-write everything by hand because it never really worked out quite that well.

I never touched UML again after university ...

Well, the code generation was a mistake, but drawing diagrams is explicitly what the guy in this story did:

He started by sitting at his desk and drawing a lot of diagrams. I was the project coordinator, so I used to drop in on him and ask how things were going. "Still designing," he'd say. He wanted the diagrams to look beautiful and symmetrical as well as capturing all the state information.

UML was an abomination, and it's a relief it's completely dead.
