On my old macbookpro, filming something like this is very near the performance-limit and therefore its possible to make some mis-mouse-clicks and so there seems to be some minimal uncorrect points that caused the end-problem, but the way would be possible.

later i found the glitch:

Hi Heimo,
Thanks for your video! It's a real piece of DIY and kind of nice to actually do that kind of manual cad work a la Sketchup. I hope GS will rethink the stair tool so that it can be more user controlled instead of programming itself into dead ends all the time. I'll post a picture of the stair when I'm done. This is my first day after the xmas holidays and watching your vid wit a cup of good coffee was a great start.
Best regards to Austria,
Mats
