The USB key (SDB) is 60 GB, which obviously is one of the larger sizes of USB key's available. I understand some people wanting to install to the device the image resides, but for the default behaviour to do this seems "quirky" as this use case I would presume would be less common. I easily got around this by clicking on "Import mount points", but new users may be thrown of by the current Yast2 default behaviour which is why I filed this report.
