no they will not you will have a space that throws it off in the middle. if you do this stuff alot, go buy the 95" rail.
or just index the holes from the top and then from the bottom. usually on longer case you have a stationary shelf in the midde. and I always go up from bottom about 8-10" and down from the top 8-10" so you can do a 6-7' bookcase side with the short rails.
Thanks for the clarification, I probably don't do enough of it to justify the longer rail but may have a compulsory need to own it anyway. I am getting ready to build all the cabinets in my house. Festool+Router Table+Leigh D4 jig=fun fun fun.
hate to talk you out of a compulsive purchase, but you can move the one rail up or dwon on your board to drill more holes. Just use a couple of dowels to register the guide for the next series.
Do have two of the FS-1080 rails? If you do you can attach the linear stops to the rail and get the correct spacing. For the life of me I can't remember whether it was with 16 or the 32 showing on the linear stops.
I know it worked when I used it on a 92" tall book shelf. There will be a gap in the hole spacing where the two rails are joined but I was able to plan for that.
If you do a search of LR32 alignment, you will find a lot of options.

I used a variation of John's idea when I needed to make 5 rows of holes in each side of a heavy duty storage cabinet so I could adjust the height of the drawer slides (rated at over 250 lbs each). I walked my short LR 32 rail lengthwise using the OF 1400 with 5mm bit installed to confirm I had the rail properly indexed. I joined a normal rail to the end of the LR 32 to enable clamping the LR 32 at the ends of my ~7 ft long workpiece, and clamped a straightedge behind the LR 32 to act as a lineal guide as I slid the LR 32 along the workpiece. If you dont' advance the LR 32 a distance more than its working length, you can slide the router back and forth to confirm that you have perfectly indexed it for the next series of hole. With this technique, you could index the length of a football field if you have a long enough straight edge to back up the LR 32 and a way to lock it in position as you make each successive series of holes.
