That's the way this ATCOCAS pish is all set up so they can control in class G.
And you won't have a clue what the company's SOP's say about that run, it may very well be that its stipulated that they have to follow the instructions to satisfy the safety case. And there is a standing agreement that they stay where ever they are told to until the runway is declared glider free and a runway inspection done.
Its not just the ATS which is involved here.
