When taking the splined sections apart such as the slip joints/yokes you would mark them. If they are assembled with the u-joints out of phase, you will get a serious vibration.
there is no need to mark it if you are just changing a u-joint.

So when the back shaft from the carrier bearing to pinion is removed, the rear wheels could spin or the transmission turn in neutral, and all is ok, correct?
And the splines go into the receiver only one way, correct?
Thank you for you responses!
I am not sure what you're asking here. One end is male and the other is female. IDK how many splines there are but none of them are offset to insure that you only install it correctly, that would be too easy. If there are 16 splines there are 16 different ways they can be put together.
I never count on any piece of equipment having a dead spline so it can only be put together One Direction. It is safer and easier to Mark it with a permanent marker so you simply line up the marks and slide it together.

Reason: Spelling
Yes, it is keyed so that it only fits together one way.
Admittedly I don't have much experience with drive shafts, and I've only had a handful of them removed over all the decades I've wrenched, but I've never come across a keyed shaft that only allows it to be installed one way.

I should have quantified. The slip yoke has the "dead spline" as HD Rider mentioned so the shaft is keyed to only fit back together one way. As for the rest of the driveshaft I've not had the whole thing out and taken it apart. I agree, though, that I don't want to rely on pieces only fitting in one place during re-assembly of a balanced unit. I always mark my driveline when taking any of it apart so I have a guide when I put it back together. Any specific fit is just a backup to let me know I'm doing it right.
The slip yoke is only one example and a small portion of the driveline. If I took it all apart without marking anything I'm pretty sure I would not put it back together exactly as it was.
I learned exactly what Brian42 just wrote. The spline only goes in the female receiver one way. If you do not mark it, you can spend the extra time finding the magic spot, or simply conform and mark it and make it easy on yourself and you assistant if one is present. I also learned my Beagle is a thief and stole my boot, now I need a new one.
