Absolutely, at the end of the day if a do gooder member of the public phones 999 and tells the emergency services a plane has just crashed you can expect a large response, no assistance radio calls or not.
It would seem thay despite the good intentions of the pilot in putting out a no assistance required radio call, a member of the public misinterpreted the situation which led to the escalation and over resourcing.
In fact, that 999 call may be the only reason the all the services turned up at all, if a no assistance call had been put out.
