Driveshaft question

[68_Step]

I dropped my driveshaft tonight to measure my u-joints for replacement. It is a 2 piece shaft. Before I removed it, I marked the yoke to shaft position so could put it back together the same way. To replace the carrier bearing I removed the bolt and pressed off the yoke. I did not mark the yoke to splined shaft position because my Haynes manual said it is impossible to put the yoke back on wrong because it is keyed. I think the book is wrong, now that I have it apart it looks like can go back together in several positions. Looking at the pics what DG o you think?
