It’s pretty much exactly as intuitive as “state of the art”—a term of art I didn’t understand as anything beyond a superlative until I had heard it for 20 years and decided to give it a think. Which is to say, not very intuitive at all, until you just pick it apart and think about how it might relate in context, and then it’s just reflexive.

First time I read "term of art" I knew exactly what was meant. It doesn't seem that obscure.

However, I was already familiar with "start of the art" so it wasn't that great a leap.
