Sorry bt I think Airbus does agree with Nitpicker.
The procedure you mention is a procedure for when you get the brakes hot indication. This is, as the title says and ABNORMAL situation, not a "pilotīs discretion" situation, and is triggered by a "Brakes Hot" indicated condition, not a "supposed" one.
Also, the procedure then goes to say "if performance permits". So it is also considering the case of an engine failure. In that case, performance does not permit, therefore gear will be retracted.
But still, my main point is you are describing an ABNORMAL procedure triggered by a specific advisory, while some people here are talking about a "pilot does as he feels like" situation.
Cheers.
