Because "speaking SQL" [even before SQL as such was even invented, hence the scare quotes] was intended as a skill to be practiced only by those who also grasped the [mathematical] logic of what they were doing when "speaking SQL". None of the people who "speak SQL" these days fit that bill.
And FWIW, what I wrote was in reply to "mental model". It was *you* who apparently equated that with "speaking English". The "mental model" I described as "exactly the problem" is the "mental model" *of the corresponding logic*, which, though mathematically consistent, is hopelessly unintuitive. Being English-speaking or not has nothing to do with understanding a particular logic underpinning the behaviour of a particular Data Manipulation Language.
