To answer your earlier question, the cropmark plot can be found in Burnham and Wacher's Small Towns of Roman Britain. Dropping it over the lidar plot is something I put together.
Retreating slightly from 'camp' , I would have to concede that even if it were part of a double-ditched enclosure (of unknown date!), that wouldn't really fit in with the morphology of temporary marching camps. That said, the corner looks entirely convincing on the photos (and as plotted on the cropmark plot) so I don't think it can be dismissed as drainage, nor is there any reason to think that area boggy. As you point out, the town itself (and the south-east corner of the fort) are at very similar elevations and there's plenty going on outside the walls of the town on lower lying ground.
