If the brake slightly locks the rollers & moreover the clutch are trying to overcome the additional drag of the rear wheel, hence heat is produced.
Given that these clutches (mines an early model) aren't the best and I understand they've strengthened the plates on later models - also having experienced on some high percentage gradients the need to have a run up otherwise experience clutch burn (two up & carrying luggage).

A drum brake will also expand on with heat if incorrectly adjusted - so needs to be adjusted on all leading edges until it rubs then backed off so it's free.
