It's the lat/lons of the corners. Additionally JOSM will give you the desired width and height of the resulting image, thus overspecifying the request (width OR height would be enough). If you cannot create a recangular image that matches all parameters, then you know that either you or JOSM have got the projection wrong. There is some special NPE map support in the WMS plugin which does some kind of re-projection, I never bothered to understand quite what it does. Nick Whitelegg would be your man to ask here since he implemented the original NPE support for the Landsat plugin, which was the precursor of the WMS plugin.
