The aircraft was obviously not configured by 1000', the IFR stable approach point, or possibly not going to be properly configured by the visual stable approach point of 500'.
I don't know if they were in cloud at 1000' feet or in VMC and simply made the judgement that they weren't going to be stable by 500', but a lot of people on this thread are going to look very silly if this crew was simply going around as per SOP due to the stable approach criteria.
