I believe that the adjective "outer" is superfluous and does not change the meaning of the sentence. "Outer space" is synonymous with "space", which by the generally accepted definition begins at 100 km altitude (about 62 miles).
What would the area between the edge of the atmosphere and lunar orbit be called then?
Why does it need a name?
That would be called cislunar space.
By this metric, the ISS is clearly not in outer space then. Nor any satellites. Seems like parent threw their sense of logic to boise as well.
