I'd say it depends on the geology in the trench, how neatly it has been machined, how visible the archaeology is, and how much spoil ends up in the bottom.
Some times an obviously 'empty' trench doesn't need cleaning.....though sometimes it should.
Depends on local knowledge of the geology/ archaeology?
