Now there is a fair argument that there are grounds for understanding that exchange (the last few sentences) to be understood as having been cleared for a visual approach. "Go Cat 6207, that's approved." , and that he was only requested to report leaving 3000' - which they did.
Sorry I cannot agree with your statement above. My bolding BTW.
I read that as...
No no, we are visual, we are happy just to make a left hand teardrop to turn back into a right hand pattern.
Go Cat 6207, that's approved.
Go Cat 6207, report turning inbound for descent.
Report TURNING inbound (ready) for DESCENT. The ready in brackets is implied by the statement "for descent".
Would like to hear an ATCOs opinion on the words.
