If the stair is set to end with a tread, then this railing option works fine.
But if the stair is set to end with riser, then this option does not work at all.
It is not greyed out as unavailable, nothing is mentioned in the user guide or on-line help (that I could see), and nothing is mentioned in the YouTube video (starting at 8.45) ...
I would rarely end a stair with a tread as I would most often use the top landing (slab) as the last tread.
I just wanted to mention this as it had me stumped for a while.
I have reported it to the Aussie distributors as a possible bug.
Hopefully it is something that can be fixed or a warning added or the option greyed out when not available.
It is not a killer problem as the posts can be positioned by other methods, but it does also affect the balusters on each tread as well.

Confirmed. Tried in AC22 and it does the same.
For me it's a bug... its behaviour does not fit with the command.

This is definitely a bug, it is on our list to fix it! It should work even if the stair ends with a riser. I updated our entry about this issue with the info from here.
Thanks for letting us know!

First, how can that possibly be what I want?
Second, why is there no offset parameter?
Third, what is the best way to move those posts back (toward the riser) to a logical position?
Thanks.

The first, and I think best, is to just reduce the height of the segment going up the stair
I believe this is fairly standard practice to achieve the continuous flow of rails at the post position (i.e. no gooseneck).
The problem with this is you will get slightly odd shaped panel which I can't see any control for.
The inner rail connection may also need adjusting (I don't have those rails in my image but I just noticed you do).
The second is to add an extra node to the reference line of the railing.
Where ever there is a node you will get a post.
Then you can delete unwanted panels and posts.
Only problem with this is that it seems the panel can not have a negative offset from the deleted post.
So it can't be stretched to the next post - I believe balusters can.

Setting a node offset will shift the post position, except for the post on the top tread... while the reference line is on the nosing... scrap that, more inconsistencies...

I think this is with regards to within the stair flight as well.

Either that or it is because that was version 21.
I find version 22 is better for railings.
This is 22.
Railing is associated to stair (i.e. placed with magic wand).
You can adjust the offset at the change of angle.
Then you just have to adjust the height of the sloping segment to form a smooth transition.
You will need to measure the height needed in elevation (at the front of the nosing/tread) and then change the segment height in 3D.
The rails all have direct connections so there is no need to adjust anything there.
Just need to adjust the height of the rail under the handrail so it looks like it is in the correct position - can be dragged by eye in the 3D or elevation (elevation is easier).

1) In order to change the segment height of one segment relative to the other you need to first "Create Independent Segments and Nodes (context or Design menu). I missed that fact and was stuck until I figured it out.
2) It would be great if the tool allowed graphic editing of the segment height in elevation & 3D. My sloped segment was already correct by virtue of being associated to the stair. All I needed to do was raise the flat segment and a simple drag in 3D would be fast and easy.
3) It seems a simple matter for the tool to perform that last set actions automatically. Keeping the top rail joined without a step is a common arrangement. An option, similar to that offered for Non-smooth Connections, that would automatically increase the adjacent segment height, would be a welcome addition.
Nevertheless I got everything to work, and learned a lot about the tool along the way. Thanks again for the help.
