Did you ask the captain to explain? I did it once on B763, but it was a short turn around on a short runway & we had brake temp gauges. They were in limits, but the following sector was also short. A couple of minutes fresh air, I thought, would make the tyres smile and be thankful. It was briefed, discussed and actioned. A complete learning process.
In your case the only contributing factor could have been weight and a HOT day. Even then it should be a procedure with general guidance from AB & the company; or was this another personal quirk?
