The A321 has certainly stopped short, perhaps in the absence of ground staff to switch the stand guidance system on? I would also guess that the A330-300 wingtips are not visible from the cockpit. However, and assuming the crew had received taxi clearance, there are other clues when judging if clearance is assured.
The A330 isn't hanging about and, looking at the impact, I wonder if the A321 could be a write-off.
