I think Maine Sail meant gaskets... not filters... fitting two filters on the engine would be a really neat trick. 
Looking at the picture it seems the OD of the filter is bigger than the on engine filter adapter. If this is the case the gasket could easily blow out. I don't recall ever seeing a filter with a diameter bigger than the filter adapter. Another potential issue that I don't recall seeing mentioned is that when the filter was changed the old gasket stuck to the surface and you then had two filters on there..
