'If the brakes were "hot" to begin with, then they should not have started the takeoff roll..'
Depends on what you mean by hot
If the brakes are 'warm' but below the 300 limit then you are safe to depart. On a short sector and with short turn around times the brakes will not cool very quickly. Therefore it is good practise, bearing in mind performance, to cool them down when you can.
We often taxy the 340 on 2 engines to reduce the brake use after landing.
