Vince lactam stereochemistry

Thanks for writing an article on this interesting compound! I am confused by the stereochemistry illustrated in the File:Vince Lactam Structure parallel.JPG diagrams. Are the structures on the right switched? For example, holding a model of the upper-left structure with the 5-membered ring approximately flat, the vinyl bridge appears to be going away rather than forward, but the upper-right equivalent has it wedged.
