Probably a mis-print in the catalog and they have fixed it in the online catalog. Look here: Track & Power Online Catalog. The page didn't link, just the catalog, so you will have to scroll through to page 25.
If you leave out the 2 - 5" straights on either end will it still fit together and fit on your table? That's the only thing I can think if without trying to reproduce it in track planning software.
There was a similar layout to this that forum member Larry3railtrains recently put together. Check this thread Extending 4 x 8 layout. Larry added a 2' x 7' extension to the end of his 4' x 8' table, but I think his plan with the figure 8 part might fit on your table. His table ended up as 4' x 10', but he added some sidings in the extra 2 feet. Take a look and maybe you can fit something together without wasting too much track. If you ask Larry, he might post his plan for you.
The track plan I am talking about in Larry's thread is toward the end of the thread, it isn't the first one shown. There are some other similar plans in there also. If you can't get anything going from that, let me know and I will try to put something together for you in RR-Track.
