These vague terms allow the builder to substitute source woods based on availability without resorting to a change or violation of their specs. I’m more familiar with Martin where they do some pretty advanced wordsmithery. “genuine” “select” “hardwood” all come into play.
I for one consider the spec sheet to be a contract between builder and buyer. The more specific it is, the better I am informed and the happier I am. I come from a building materials background where the specifications are law and the only thing to keep contractors from cheating. So, I view it as very important what’s shown in these guitar specs and when I buy a guitar, I expect them to conform, without deviation, from the published specifications. Otherwise, it’s false advertising in my view.
